2) 1 person bad does not make all people bad
This may go against "SV standards", but I've found that the execs that I most admire at any particular company put in at minimum 4 years - that's the time it takes not just to get a project or two off the ground, but to really instill structural and cultural objectives at any company, and as you put it , to really deal with the consequences of their decisions and refine as necessary. While everyone have some "misfires" in their career, I'm extremely wary of advice from someone that has literally never hit the 4 year mark despite nearly 2 decades of experience.
the people who are in-deep for decades 1) have no time or motivation to write/build a brand^, 2) have political reasons you can't write anything insightful esp while your own house is messy (and it never isn't).
so how to change this?
my approach is to run a conference where practitioners do short ted-talk-like-but-technical talks about their work and learnings while still on the job. but ofc they all have their own motivations to speak.
^ though i will be the first to say that you CAN be primarily self-motivated to write-to-think-out-loud and this is a thing, do not let jaded HN people tell you different
