The reason they are still getting money is the image they are upholding together with their echoing fanbase.
2) Sure they are trained, but similar does the UT Austin kid find out about business models and applies to YC then, to go go right away to the A players.
Don´t get me wrong -- nothing against content marketing or USV. But the market tectonics have changed. If you are a relatively small fund like USV, you technically cannot afford anymore to preach from the high horse. On one hand-side the VC whales are eating you lunch and on the other hand-side corporate investors can invest much more than you.
Put to simple terms: USV didn't grow fast enough and are now stuck in the middle. They cannot do enough (small) deals to leverage an average of their bets and on the other hand side, entrepreneurs are much smarter.
How many people are at USV, 8 maybe? By all science, they have no chance to be smarter than the (much more connected) market anymore.
