> What's the point of going on if you can't contribute?

Because "peak" isn't required to contribute.

I strongly suspect I can't program like I can when I was 25 when I could hold a gazillion details in my head simultaneously--now I simply find a task that requires that to be distasteful.

I am, however, MUCH better at architecture and organization so that I don't have to hold a zillion details in my head. That also means that my programs are far easier for others to understand than the ones I wrote when I was 25.

Which one is the better "contribution"?
