However that's not the only thing that matters. What also matters is the inherent complexity of whatever problem it is that needs to be solved. The vast vast vast vast vast majority of problems are unsolvable in principle because they would require taking all the material in the universe and turning it into a computer running at the upper limit of computation in order to compute, and even then they don't actually come close to finding a solution.
