Can you think of an example in history where labour was replaced with tech and the displaced workers kept their income stream? If a machine can do your job, (eventually) I'll be cheaper to use that machine instead of you and you'll no longer have a job. Is that not a given?
Anyway, it was probably just a joke... so not sure we need to unravel it all.
Displaced hired personnel of course cannot hope for that.
But VCs own their business, they are not employees. If you own a bakery, and buy a machine to make the dough instead of doing it by hand, and an automatic oven to relieve you form tracking the temperature manually, you of course keep the proceeds from the improved efficiency (after you pay the credit you took to purchase the machines).
I didn't get the impression it was meant as a joke:
"Every great venture capitalist in the last 70 years has missed most of the great companies of his generation... if it was a science, you could eventually dial it in and have somebody who gets 8 out of 10 [right]," the investor reasoned. "There's an intangibility to it, there's a taste aspect, the human relationship aspect, the psychology — by the way a lot of it is psychological analysis," he added.
"So like, it's possible that that is quite literally timeless," Andreessen posited. "And when the AIs are doing everything else, like, that may be one of the last remaining fields that people are still doing."
