I think it's mindset. I came to computers late, at work, and was not well introduced. But people fifteen years
older than I took to computers. I believe it is both the way ones brain works (or doesn't) and where your skills
lie. I have done some math with facility -- plain geometry where the proofs are advanced in language, and
a little trig with some help from my friends, but I had a non-verbal teacher (really) for algebra and couldn't
keep the inside of the parentheses clear from the outside, and barely passed. Some people synch right in
with computers, regardless of age, and find even the most frustrating resistance within a program a sort of
fun game that rewards persistence and trial and error, and pretty soon they get what they want. I find the
resistance from a program alienating and frustrating. It feels counterintuitive and insulting, even though the
machine has no attitude or consciousness at all. Some minds are built for the binary logical mode and others
think and learn differently ... and alas, that's me. A new device always fills me with resentment.
