Who says it's optimism?
The fact is the technology is growing ever faster, even the current AI models are far better and more sophisticated than the ones that appeared last year and that's only been a matter of months. As every single expert will tell, the 'AI' of 15 years ago (if one can even call that AI) is absolutely nothing compared to what's around free to use nowadays, not even a fraction of 1%. That's not a matter of optimism or pessimism or "I have been around longer, so I know better", it is simply what it is right now.
The big question is what's going to happen with it, because it 100% will keep developing and that's not going to slow down by any stretch in the next few years. One can either try to stop it, which is just not going to happen (the billionaire tech companies are developing it after all, they're not going to stop), or somehow try to incorporate it in one's technology, learning and so on.
I am not optimistic about that entire situation at all, for what it's worth. I don't see it as a majorly good development, but it is a development nonetheless.
