Yeah, I'm definitely not saying this is already the ultimate solution. But if you look at their scaling experiments and extrapolate the results, it roughly shows how a model with number of parameters on the same order of magnitude as the human brain could more or less achieve overall human level performance. Of course that doesn't mean the architecture has to extrapolate, but it's definitely a path worth walking unle…
Except it is pretty naive to extrapolate like that. A high order polynomial looks flat if you zoom in enough. You can't extrapolate far beyond what you have empirical data for without potentially running into huge problems.
How do you know what the function looks like? Unless someone shows that this scaling behaviour breaks down, it is definitely worth pursuing, since the possible benefits are obvious. Everyone who just says it will break down eventually is almost certainly right, but this is also a completely trivial and worthless prediction by itself. The important distinction is that noone knows where the breakdown happens. And from what we can tell today, it's not even close.
