Ok, but by that same perspective, you could say convolutional neural networks have been around since the 80s. It wasn't until Geoffrey Hinton put them back on the map in 2012ish that anyone cared. GPT2 is when I started paying attention to LLMs, and that's 5 years old or so.
Even a decade is new in the sense of Laplace's law of succession alone indicating there's still a 10% chance we'll solve the problem in the next year.
I have to hard disagree here. Laplace's law of succession does not require that assumption. It's easy to see why intuitively: if it turns out the probability is 0 (or 1) then the predicted probability from Laplace's law of succession limits to 0 (or 1) as more results come in.
