Is that true though? To me, the difference between a simple spreadsheet and say, a floppy bird, is that the spreadsheet requires one to know about rows and columns, and basic math (sum, average). It's a pretty simple abstraction that matches, say, a sheet of paper with a list scribbled on it.

Whereas, say, flappy bird, requires you to think about a lot of other abstractions one is less familiar with, and juggle those. User input, graphics. I think it's the complexity of abstraction and the difficulty of reasoning about it and juggling all the bits in your head, that makes it hard. I think that's a skill you really have to have or learn. Just because some people van add two cells doesn't mean they can easily create their own abstractions f.ex
