It means trying to figure out how to build an intelligence always loses to mindlessly brute-forcing problems with more compute:
There is nothing particular that suggests this is infinitely scalable.
If that really isn't an option, then yes ML/AI isn't for you in this case.
The 10,000 hours thing is encouraging because the amount of effort you put in as far more important than your natural ability.
... Until you get to the point where everyone is already working as hard as humanly possible, at which point natural ability becomes the sorting function again.
