The AI technology we’re using isn’t “new” the core idea is several decades old, only minor updates since then. We’re just using more parallel processing and bigger datasets to brute force the “advances”. So, no, it’s not actually that new.
We need a big breakthrough in the technology for it to actually get anywhere. Without the breakthrough, we’re going to burst the bubble once the hype dies down.
So, uh, no? In fact within the “human spectrum” you generally care at least somewhat about every tick of the number. So it’s actually more useful for people.
Because I doubt you can feel the difference between 71f and 72f. But it’s possible to notice the difference between 21 and 22, although you’re pretty picky if you do.
