The 100 year career

Oxford university scientists expect us to live to be 100+ with many routinely expected to reach 150 years. Working life will, thus, last well into 70s, 80s and even past 100. How might we approach a career if we knew it was going to last 100 years?

Here are six ideas –

  • Regardless of the career you choose, approach learning like a chef. When you learn something, focus on building the skill to reason from basic ingredients/first principles. Learning how to learn is a high RoI skill because you will need to learn many different skills over a 100 year career.
  • You don’t have to prove anything to anybody for a really long time. Judging your success in 25 years will be like awarding the NBA title to the team leading the score in the first quarter. Again, we’re talking about 25 years.
  • Retiring early is a misnomer. Instead, if you want a way out of your lucrative but uninteresting career, look to get wealthy enough by your desired age so you can spend the next few decades working on ideas that interest you. And, if this path is avoidable, you may want to consider it. Also, if you’re a university administrator, I hope you’re planning out your continuous learning curriculum.
  • It will help to find work you enjoy or feel passionate about. A great way to do that is to get incredibly good at whatever you are doing. We love things we are good at.
  • Your biggest performance improvements will come from improving your attitude. A growth mindset that allows for openness to new ideas will be your biggest asset.
  • Don’t let a setback in your next expected raise or promotion get to you. You’ve got time. :-)

Of course, these ideas apply just as nicely to any career. Maybe we should adopt them regardless?

Quantum Computing — Superposition Of Optimism And Pessimism

‘Nature is quantum, goddamn it! So if we want to simulate it, we need a quantum computer.’

Those words from Richard Feynman’s keynote in the “First Conference on the Physics of Computation” was what researchers in the then nascent field of quantum computing needed to hear. It gave the field the boost that it needed to begin a multi-decade long search for the first working quantum computer.

Classical computing. In 1948, MIT Professor Claude Shannon published a landmark paper — “A Mathematical Theory of Communication.” In this paper, he laid out the basic elements of communication (transmitter, channel, receiver, etc.) and popularized the term “bit” as a unit of information.

The bit remains the building block of the computers and phones that we use today. And, thanks to Shannon’s model and breakthroughs from numerous other researchers, we were able to use computers to solve many hitherto unsolved problems.

However, there classical computers cannot tackle very complex problems because it would require insane amounts of computation. For example, cryptography relies on the fact that no classical computer can break a large number into its various prime factors (e.g. 15 has 2 prime factors — 3 and 5) easily. A 232 digit large number took scientists two years to factor using hundreds of classical computers.

So, why can quantum computers do more? Super position and Entanglement. Classical computers encode and manipulate information as strings of binary digits — 1 or 0. Quantum bits, on the other hand, can exist in a superposition of the states 1 and 0. This means that a qubit’s state could be 1 or 0 with some probability.

Next, to perform computation, these qubits must exist in an interdependent state where changing the behavior of one can affect the other — this is called entanglement. This means that operations on qubits count more than on simple bits. While computational resources increase linearly as we increase the number of bits on classical computers, they increase exponentially on quantum computers. So, adding an additional qubit roughly doubles the computation power => a 50 qubit computer has 2⁵⁰ computational power than 1 qubit computer.

Error rate. The challenge, however, is error rate. Random fluctuations, from extra heat in qubits for example, can change the state of a qubit and derail the calculation. So, quantum computing can only live up to its potential if all the qubits work “in coherence.”

This is a problem because a high error rate takes away any benefits of using a quantum computer.

Reasons for optimism and pessimism. 2017 was a year that brought reasons for optimism with it. IBM announced that they had created a 50 qubit quantum computer. Google and Microsoft have also been investing heavily. In addition, IBM has made a 5 qubit computer available to researchers since 2016 for free.

While all this is good, there hasn’t yet emerged a solution to get around the error rate. While some researchers believe error rates will be the reason quantum computers will never make it to the mainstream, researchers around the world are working hard on the problem. Some believe the solution will be finding a way to work with the noise rather than to eliminate it. Could there, for example, be quantum algorithms that will enable us to generate results despite the noise? There is no guarantee we’ll find a solution however.

The next hairy question is which problems will quantum computers help us solve. While there’s a debate here, it is clear it won’t be a cure all for all sorts of problems. Besides if a quantum computer’s error rate is hard to predict and if its calculations can’t be checked, how can we conclude that the problem is solved right?

We have more questions than answers at this point.

Where does all this leave us? I really struggled with putting this post together. I postponed writing it for 2 straight weeks despite reading and watching the articles and video below at least a couple of times because I wasn’t sure I understood it well enough to write about it. I finally decided I’d ship my draft today no matter what.

That, in some ways, gets to the challenge with quantum computing. It is hard to understand how it works, why it is better and, thus, what it could do.

My layman’s synthesis, then, is as follows –

  • After nearly four decades of research, we’ve made a lot of progress in quantum computing in the past 3 years. This is thanks to our ability to build quantum computers with more potential computing power than any classical computer.
  • Quantum computers will not replace classical computers. Instead, we will use them to help us solve certain kinds of problems. For example, they may help us make progress in understanding the workings of complex chemical reactions which may, in turn, help us cure challenging diseases. They may also do better at complex optimization problems than the best deep learning algorithms.
  • However, realizing this potential requires us to figure out how to deal with the “coherence” problem that results in error rates.
  • There are various groups working on solving error rates. The solution might be to build algorithms that work despite them. As a result, getting more researchers and programmers to work on quantum computers is going to be key. That said, there is no guarantee that we will find a solution.

It feels like we’re still a couple of decades away from quantum computers hitting the mainstream. But, making such predictions on technology I barely understand is likely foolhardy anyway.

So, I’ll end with a note on the topic. All my reading led me to the conclusion that the way to think about the outlook on quantum computing is simply to think of it as a superposition of optimism and pessimism. :)

1 to 2 and 3 to 4

We welcomed our second baby a week and a half ago. I thought of the three things that I expect to happen this morning.

First, I expect to learn a ton about myself as I adapt and change how I operate. I expect to struggle through the process of more developing more flexibility and more patience while understanding how and why I make decisions the way I do. It will be a fascinating process.

Second, I expect to understand and appreciate the sheer magnitude of my wife’s contributions to this partnership a bit better. Research has shown that we all like to think of ourselves as above average contributors. While I know I’m not above average in this partnership, I expect to learn I’m likely still overestimating. We’re now at eleven years since our first date and approaching five years married – we’ve both learnt a ton about what it takes to be good partners. I don’t write enough about the importance of marrying a true partner as we’re both pretty private and wouldn’t want this blog to start having frequent public displays of affection. I slip every once a while. It is hard not to as she is a true, un-credited, co-author.

Finally, I hope to re-commit to Kahlil Gibran’s profound passage – “On Children.” It is our aspirational parental philosophy.


On Children by Kahlil Gibran

Your children are not your children.
They are the sons and daughters of Life’s longing for itself.
They come through you but not from you,
And though they are with you yet they belong not to you.

You may give them your love but not your thoughts,
For they have their own thoughts.
You may house their bodies but not their souls,
For their souls dwell in the house of tomorrow,
which you cannot visit, not even in your dreams.
You may strive to be like them,
but seek not to make them like you.
For life goes not backward nor tarries with yesterday.

You are the bows from which your children
as living arrows are sent forth.
The archer sees the mark upon the path of the infinite,
and He bends you with His might
that His arrows may go swift and far.
Let your bending in the archer’s hand be for gladness;
For even as He loves the arrow that flies,
so He loves also the bow that is stable.


Our son’s name is “Ved” (pronounced “bathe” with a v). It means knowledge. It felt fitting…

The misunderstood relationship between financial risk and entrepreneurship

Writing about entrepreneurship often defaults to featuring entrepreneurs as adventurous risk takers. And, generally, it focuses either on the world famous list of college drop outs (Bill Gates, Mark Zuckerberg, Sergey Brin, Larry Page, etc.) or Elon Musk (who is in a category of his own). This is both lazy and misguided because it misunderstands the relationship between financial risk and entrepreneurship.

None of the above folks took significant downside financial risk when they started their companies.

Brin, Gates, Page and Zuckerberg were drop outs from Stanford, Harvard, Stanfard and Harvard. They could have gone back to their prestigious schools if their companies didn’t work out. And, in the worst case, they would have ended their careers with tens of millions of dollars given they were setting out as programmers in an age that valued that skill.

Elon Musk didn’t set out to start SpaceX when he immigrated to the US. He struck gold with Zip2 first. His appetite to put his reputation on the line is commendable – but, let’s not confuse that with financial risk. He could lose all his money and make millions writing books and speaking if he ever wanted to. That he doesn’t is wonderful. But, let’s not pretend he’d be living on the streets otherwise.

In his book, Originals, Adam Grant has a good section on the real relationship between entrepreneurs and financial risk in a study of Warby Parker. As Warby Parker’s founders demonstrate, entrepreneurs actually need to masters of de-risking their venture. That’s why the best are obsessive about testing, rapidly iterating and finding product-market fit.

It is easy to see this in action when you are in any entrepreneurial hot-bed. Entrepreneurs rarely go out and put their savings on the line. Instead, they build a prototype on the side, attract enough venture capital interest and THEN quit their jobs to build a company. The existence of venture capital and (relatively) easy financing is key to entrepreneurial ecosystems. And, I’d argue that it is the sheer density of financing options in the Bay Area that ensures entrepreneurial minds, on average, find their way here and not the other way around. Regardless of causality, one wouldn’t exist without the other.

Finally, we generally discount the importance of privilege in the role of success. In all of the above cases and in most such stories, these entrepreneurs were based out of the United States – and often into families that had the capacity to help them if things went south. Family wealth aside, the right zip code is the biggest source of privilege on the planet. The best zip codes make it easy to build companies with plentiful access of capital and view failure as experience for the next attempt at building a successful venture.

What does all this mean? I think there are two lessons here. The first is to be dig deeper into stories that talk about entrepreneurs taking on heroic levels of financial risk. That’s not to say there won’t be exceptions. Instead, you’ll find that the exceptions prove the rule.

And, second, pay attention to conventional advice. Get to the best zip code possible, earn good educational credentials and work yourself into a position of privilege. The seeming risks that you take from a position of privilege won’t be risks at all.

Compare purchases to put them in context

We think of money differently depending on the context. For example, we may fight for a three hundred dollar discount when buying a new car. But, the same discount when buying a house would feel ridiculous. It is still the same three hundred dollars, isn’t it?

The downside of this approach is that we may be biased toward making certain kinds of investments over others. And, one tool I’ve begun to find helpful is to compare purchases to put them in context.

Let’s imagine you want to spend $100 on a hobby. It is tempting to think you’re rationally evaluating the cost/benefit of the $100. But, we’re not rationally evaluating anything – instead, we have a certain dollar amount threshold tagged to hobbies. So, I begin asking myself – what are other areas where I’m spending $100 or more? Let’s say I’ve got a vacation coming that’s got a budget of $1000. How would I think about adding $100 to the vacation with a new, cool add on? How much does that compare with the added benefit from the hobby?

Or, what about that gadget you’re considering buying?

After two or three such comparisons, it becomes obvious as to how much you value the expense you’re considering. In my case, for example, I found myself biased against making a couple of expenses that had some short term hassle and longer term benefit. I also realized I had a bias against annual subscriptions over one time payments.

My goal with expenses is to do so consciously. And, comparing purchases helps with that.

I hope it helps you too.

3 principles of asking for favors

Asking matters. We all do it. We could argue that we all need to do more of it. Here are 3 principles that might help –

i) Optimizing for quality works better than quantity in the long run. It is always tempting to send that mass email or send bulk LinkedIn invites with that generic message. There’s a reason they need to be sent in bulk – they rarely work in the short term. And, sadly, they backfire in the long term. Instead, over-invest in demonstrating your research and thoughtfulness. As Seth  wisely put it – “Don’t personalize, be personal.” While choosing volume may seem less risky, letting quality dip in any interaction is the riskiest thing we do in the long run.

ii) Avoid planting trees the day you need your fruits. “Hi, I don’t know you. Nice to meet you though. And, can you please do me a big favor?” If relationships are like trees, most folks ask seeds for fruits before they touch the ground.

One way to proceed is to think ahead and build the kinds of relationships that you think you might need (some do this artfully). My bias would be to just let curiosity, great intentions and care be your guide. Meet or e-meet folks whose work and voice inspires you. Over time, a few of these will turn into relationships. And, when it comes time to ask for fruits, you’ll have plenty of options.

iii) Get into the habit of granting favors yourself. For every favor you ask, help at least 5 people who seek favors from you. Do it so often that you don’t even think about doing them. Karma. It matters.

As a bonus, you’ll also learn to appreciate great asks and get better at asking yourself. And, that’ll take you right back to principle 1. :-)

Vacuuming and how work becomes meaningful

Vacuuming the home has been an ever present on my list of chores over the past few years. I cared about doing a decent job as I understand why it matters. But, it was never fun.

Until I started strapping our 6 month old baby and vacuuming the home with her.

At first, she mostly watched in silence. Then, she grew to enjoy it. And, twelve months later, it wouldn’t be the same without her. The issue is that she’s reached that point when the carrier isn’t comfortable anymore. I know it isn’t going to last for much longer – but, boy, was it a blast while it lasted.

This experience with vacuuming speaks to how work becomes meaningful. The first step is for folks to understand the “why.” Why does what they do matter? Once they understand that, merging the “why” with “who” they care about makes important work feel both meaningful and playful at once. It is these sorts of environments that make for incredible laboratories to grow, learn, and experiment.

And, in environments where people combine learning, meaning and fun, they do the work (the “how”) with great care.

This is the reason powerful visions need to co-exist with a great culture. It is the culture that ensures that people feel the kind of belonging to continue to find meaning in what they do. A vision is useless without strategy. And, culture is strategy in the long run.

PS: Getting back to vacuuming for a moment – it is another one of those reminders that the days are long but the years are short.
