There's an important implied point that isn't really talked about in this article: the points about learning in startups are mostly only true if you are a founder or an early employee. The definition of "early" depends on the eventual size of the company. If you are employee #10 and the company grows to 500, you will have learned a ton from the journey. But if you are employee #100, likely not much actually changes for you, and if you join as employee #500, you likely won't learn much from the journey to 1000, if your company makes it to 1000. After spending a bunch of years in startup land without seeing great success, I still learned a ton as a founder/early employee though, and I absolutely don't regret doing it. However, I've concluded that if you're looking at opportunities to be a mid-late employee, either make sure you're paid well for it, or go to a big company.
