To be fair, Sam Altman has seen the early stages of lot more unsuccessful companies than pretty much anyone has seen companies at all. Plus, he explicitly says that a lot of unsuccessful startups have some of these traits, so it's not like he hasn't considered the idea.

I think it's pretty unlikely that he's not taking unsuccessful startups into account. But it's not a statistical paper, it's an essay. You can't attack the guy for not including likelihood ratios and p-values in his prose.

"Sam Altman has seen the early stages of lot more unsuccessful companies"

Sam Altman has experience with a particular group of companies. A small subset of companies out of a huge set of people who do business. In a wide variety of places.

This writeup certainly makes some good points but it is specific to companies of a certain type and Sam has not qualified that at all in his post.

"than pretty much anyone has seen companies at all."

I've been observing companies (as have many other HN readers) since before Sam was even born. (I started my first company right out of college and that a very long time ago.)

"I've been observing companies (as have many other HN readers) since before Sam was even born."

OK, fine. If you have lots of relevant experience, then write a counter-argument that's more substantial than "selection bias!"

I'm sure we'd all like to read a comment that outlined some specific, well-thought-out points of disagreement with Sam's arguments.

"[...] well-thought-out points of disagreement with Sam's arguments."

I see mostly opinions, not arguments. An argument is generally what follows if you ask someone "why?".

> "it is specific to companies of a certain type and Sam has not qualified that at all in his post"

In the very first paragraph, Sam writes "It’s from personal experience and I’m sure there are plenty of exceptions."

What should be done to satisfy people like you?

Employees was just a simple example to help illustrate to my parent why survivorship bias matters.
