The biggest take-away for me was that, at the least, he acknowledged that it's irresponsible to gamble his family's well-being on a long-shot startup idea.
Tech culture right now prizes irresponsibility. The youth fetish is one aspect of it, but more generally, it's founded on unrealistic (irresponsible) promises and mostly bad decisions (drop out of school to work for a startup! move to the most expensive city in the U.S. with no connections!) that pay off infrequently. No one talks about how demoralizing, difficult, and wasteful it is to rebuild your savings and career after something like that fails. It's atrocious, but most investors have a vested interest in downplaying the long-term risks.
There are thousands of people like me who are smart as fuck, played the startup game unluckily, and ended up in second-tier careers compared to what they should've had with their age and ability, and would've had, had they not gambled stupidly. Most don't talk about it. They're ashamed. I'm not ashamed. Well, perhaps I'm slightly embarrassed, but (a) I'm still smart as fuck and (b) not embarrassed enough to let the next few thousand fall into the same goddamn trap, because someone has to fucking be responsible.
