But the fact that there's so much low hanging fruit is kind of the point. AGI as a field is still in its infancy. It's pure research and will be for a long time.
So if you want "Carmack's Theorem" or "Noelsusman's Theorem" to appear in high school math textbooks 500 years from now, this is the best time to jump in. (Assuming there are still textbooks 500 years from now.) "Doom" probably won't be remembered by then.
I won't be around but 500 years from now the chances are much better than even that Doom will still be around in some form and a couple of people might even know who wrote it back in the stone age of technology. Not so sure about Carmack's Theorem.
