Late 2025, "its PhD-level knowledge of every field". I just don't think you're going to get there. There is still a fundamental limitation that you can only be as good as the sources you train on. "PhD-level" is not included in this dataset: in other words, you don't become PhD-level by reading stuff.
Maybe in a few fields, maybe a masters level. But unless we come up with some way to have LLMs actually do original research, peer-review itself, and defend a thesis, it's not going to get to PhD-level.
I've been a Signal beta tester on iOS for as long as I remember, knowing that they were going to introduce usernames, and I wanted to get my (relatively common) name as my username. Now they finally introduced it, but they require it to end in at least 2 digits "a choice intended to help keep usernames egalitarian and minimize spoofing".
Edit: this is not actually a serious problem for me, don't worry! Rather, I think it's funny. And honestly I kind of like having the numbers required, it's a good idea. It does remove a lot of the vanity from usernames.
