“I still have the illusion that when I play with ChatGPT, that it’s in principle not doing anything that I could not do if I had Google at my disposal and I get all the resources from the internet and spend enough time on it. But this thing that I have an extremely autistic stupid intern in a way that is extremely good at drudgery, and I can offload the drudgery to the degree that I’m able to automate the management of the intern is something that is difficult for me to overhype at this point because we have not yet started to scratch the surface of what’s possible with this.”
