I'm sorry, but I don't understand why wider & deeper networks won't do the job. If it took "sufficiently large" networks and "sufficiently many" examples, I don't understand why it wouldn't just take another order of magnitude of "sufficiency."
If you look at the example with the blue dots on the bottom, would it not just take many more blue dots to fill in what the neural network doesn't know? I understand that adding more blue dots isn't easy - we'll need a huge amount of training data, and huge amounts of compute to follow; but if increasing the scale is what got these to work in the first place, I don't see we shouldn't try to scale it up even more.
This is my problem with the thesis that simply scaling deep nets to new heights will ultimately subsume all brain function. If it takes weeks to train a simple object recognizer deep net, how long would it take a grand unified deep net to learn to tie its shoelaces? Puberty?
