Whereas there were no programs being used and now they're being used . I was able to use my brain and compete for quite a while.
Now there are equations being solved faster than I can read them.
There does need to be restrictions to avoid AI. BrainMath or BrainCypher are only going to involve human brains until humans program new scripts to speed up their own brains.
Yes we need things that humans can solve faster than machines. I believe generated crossword puzzles with a hint might be good. A machine would need to compare a dictionary against any possible combination that seems hard to program and is probably not efficient.
