Thing is, we've had a unique situation in recent years where trillion dollar companies have seen startup-like growth quarter after quarter. Of course no one can predict the future, but I personally think this growth will stabilize to more traditional levels (see the history of the tech industry up until ~2010 for example). This does not mean that the VC industry will disappear and startup bubbles will stop being a thing. It will just be slightly more "boring" to get a job at Google or Apple the same way it was at Cisco or IBM back in the day, and top talent will want to look elsewhere for more risk and reward.
