"All models are wrong, some are useful"

I did a 10 session package (got it on sale) that focused on (distributed) system design and ML system design. I felt confident in the coding piece, but I didn't have the opportunity to work on large scale systems in my previous role. I believed that I could obtain a sufficient level of knowledge by self-study and practice, but I also have a toddler that takes up a lot of time and energy, so I wanted to be more efficient. I think it was valuable to absorb knowledge from a mentor that has real experience working in my target role. It turned out that was very successful in my real interviews. I think that I would have still done OK had I not done the interviewing.io, but, by my estimate, the return on investment was high, since I received multiple offers and negotiated up.

e: I wanted to add that my mentor and I decided that we would do 4 pure teaching sessions, and then the remainder would be partial mock interviews that would transition over sessions from them doing most of the talking to me doing most of the talking. I found this format to be good for building my own confidence.

Sure, it is generally wise to keep your guard up when reading things on the internet (or any source). That's fair enough. But at the same time, I don't think it's unreasonable to expect HN posts to adhere to a higher standard. IMO HN is not the appropriate forum for pseudo-intellectual gotchas.

TBH this post should probably be taken down, or at least explicitly stated as an April Fools joke in the title. I almost didn't come to the comments section, and I didn't read all the way to the bottom date. I definitely would have taken this as fact.

I have a pretty good relationship with my boss (not a CTO, but a member of the executive leadership at my company). I definitely do consider her a mentor to me, and I am certain that she considers me a mentee. Over the last few years she has explicitly gone out of her way to help me improve my leadership skills. Not saying that this is kind of relationship is common or not, but it does exist.

I do agree with the overall content of your post, though.

I'm guessing "Facebook, Amazon, Apple, Google, Twitter"

This is exactly the conclusion that I came to before I also left astrophysics for industry. In order to outweigh all the cons of working in academia, you really have to have a deep passion or obsession with the particular problem you are researching. In my opinion, being _just_ interested is not enough, and that's where I found myself. I drove myself down the academic career path because I thought I would find meaning and purpose there, but when I didn't find it all of the pressures and toxicity of academia just didn't seem worth it. It's only been two years since I left, and sure there are some things that I miss, but I definitely do not regret leaving.

This is not a direct reference to the linked Nature article (which is essentially a review article, I think), but Taleb is definitely a fan of Peters' work [1].

I did a week-long silent meditation retreat in Thailand a few years ago. I thought it would be difficult for the same reasons you mention -- I tend towards night-owling and loathe the thought of not eating for more than a few hours. It turned out to be much much easier than I expected. Without electronics and other sources of artificial light the circadian rhythm shifts to the sunrise-sunset cycle pretty rapidly. I slept quite well for the majority of my stay. As to the food, I think we're just conditioned to think we need way more than we really do. Eating two meals was only hard the first full day, and after that it felt fine. The meals were on the large side so it wasn't a large calorie deficit, if any. I definitely encourage you to try it if it's something you're interested in, you may be surprised at what you're capable of.

e: in light of what jason_slack said - your experience may vary, of course. Just saying that personally I did not find the sleeping/eating situation to be too difficult after a couple of days. My biggest struggle was actually sitting on the ground for so many hours per day. My hips and legs have become so tight from chronically sitting in an office chair that maintaining good posture on the floor was very painful for me (I've actually since started stretching regularly to work on this).
