If I were to bet on it, I think we'll see the tech industry move to a model that mirrors the financial world, with fixed year end bonuses, and no equity opportunities. That's what this thread is basically advocating for, even though right now it means working at Google and getting options.
$1b+ Venture Funds and employees getting generous equity grants don't match. I don't think VC is going away as an asset class anytime soon, and I don't think fund sizes will be dramatically (3-5x) smaller.
If anything, I'd say it's probably for the best for the average person working in tech. Most startup options aren't worth anything, and are highly illiquid.
