A reality is, experience generally pays and leverages.
On one hand, being inexperienced leads to a great deal of openmindedness, which despite being exciting as hell, can fall prey to chasing shiny objects and not being able to think big enough or see big enough to stick with something for a few years.
Take the small group of new entrepreneurs who launch, and many inevitably get forced out by having growth CEO's come in. What if they leveled up so VC's couldn't replace them as as easily?
Experience who doesn't become close minded, jaded, or burnt out in their 20's after chasing VC's as paying customers instead of customers as customers.

The point _you responded to_ is saying that silicon valley investment favors youth because they can get better ROI by working younger folks harder and extracting better terms.
