This is generalized, right? It can take some time, but the tasks are still being absorbed by the models at a frightening rate. We know that it is highly likely that they can replace these jobs.
It's simple really. If the VC's don't move the money, then it's dead money to them. These are calculated risks that they absorb under the premise of regret minimization. They don't really have a choice but to take occasional losses. It's nearly intentional.
