You're right - it's super easy to bounce around from one rich person to the next, trying to get fat cheques from them for your unproven and almost-certainly-going-to-fail hardware startup that would only work if enough other rich people also give you big cheques, based on nothing but a pinky-promise that you'll try your darndest to invent, manufacture, and sell cars well enough to get them their money back, one day, maybe, if all goes perfectly.

Why don't you do it too?

Raising capital in a new industry sucks, lol. A cushy job is still a job, and the human brain does a REALLY good job at building the same amount of attrition across roles in relativity - whether you're breaking your back in the mine or cold-calling 400 people a day from a Herman Miller chair.
