I was in the Tech game back in the late 1990s and in the Tech Startup game recently and this time around it's not techies that are Startup Founders, it's people from Sales, Marketing and Finance.
The whole "making something cool" ethos of Tech has been replaced by "Find a market niche that you can grow in until you have an exit strategy (IPO or sale to a larger company)" or in other words, make a company that looks like an infinite growth venture and sell it to some suckers for a ton of money.
As it so happens I was in Investment Banking in between those two periods in the Tech industry and immediatelly recognized the same spirit as in Investment Banking when I went into Startups in the late 2010.
At least the previous generation was driven by the "play with computers" drive. This one is all about borderline fraud (often outright fraud - just think Theranos or all the "coin" "tech startups") in the pursuit of personal upside maximization.
