So I think if you want to see more people with my dream then push towards a post scarce world. We'll still have plenty of resource constraints, but it does change the game a lot. I think you'll see more artists as well. A new renaissance. But I fear the transitionary period might be quite difficult and disruptive. I do think such a future has a fairly good probability of happening within many of our lifetimes and almost guaranteed if we actively pushed for it (or solved adjacent problems like HLI).
So don't be so pessimistic. There's millions of people out there that are interested in pushing the bounds of human knowledge because that's what they want. I'd argue that physicists and mathematicians wouldn't exist if this weren't true. They get paid shit for extremely difficult work. We could say the same about many sciences. While not all of these people are in it for bettering humanity (just for pursuing knowledge) it often aligns and there is a decent portion who believe this is the point of science and our purpose, as humans, in life.
There's also the ethical question. For example, duckduckgo will show you stack overflow answers. Google could easily do this but they have already gotten flack for displaying answers and taking away clicks from sites, which means reduced ad revenue for the resource actually being used. We could make even stronger arguments about services like ChatGPT in their current form, let alone the one we're talking about.
If we think a bit further in the future there's another extension that might not be what we want. Suppose our model contains all current human knowledge and can accurately give you answers and even produce paragraphs at will. This kills off a lot of websites. Is this a good thing? Suppose we incorporate an image generator along similar lines and now we have text and image search. That's a huge centralization force. There are a lot of great benefits to this that I don't want to downplay, but we should also think about if this is actually what we want because there are downsides too.
I thought I should also add that I had an at length discussion of these LLMs being Stochastic Parrots (an how we know they are) in a thread from 2 days ago https://news.ycombinator.com/item?id=34113011
