Sure we're all making software which is just bits in memory, but I think that's an extreme simplification. Maybe you're thinking of how we're all just editing text to make programs? But then that doesn't account for what you do with the program you just wrote.
I think you're thinking of using more horsepower for strong scaling, which is a good use, but I'm more referring to weak scaling. You can work on bigger problems with more horsepower, not just solve the smaller ones faster.
