Same goes for working at Google as your only job then writing a definitive book about how SWE is done, without further research on what else is out there.
However, it also means that saying things like "take a risk, do the work, put yourself out there" does not make sense for most people because they lack an unfair advantage.
"Here is how I did X" stories are almost always useless for 99% of people because they gloss over unfair advantages like e.g. went to Stanford/Harvard/other, have VC connections, worked at X company, etc. Most people cannot replicate the initial state of these startup stories, let alone the end result.
There is no comparison here with a gym membership or having limbs. Both of those are many orders of magnitudes easier than say, getting accepted into Harvard or passing an interview loop at Facebook.
I read very few startup stories that I can actually relate to.
It's sort of like all those Amazon reviews that used to say "In exchange for an honest and unbiased review, I received the product". Before Amazon auto-removed them, they were a strong negative quality signal.
I would prefer if we preserve high comment SNR by encouraging people to use standard comms patterns so that my automatic comment bucketing will allow me to skip non-useful comments, e.g. correlation is not causation, survivorship bias, etc.
