A computer won't get bitchy if you're slow to respond. A computer won't grade you on how much you send it. A computer won't look through your checkbook. A computer won't mind how many other accounts you have, or if you keep getting new ones. A computer won't shave with your razor.
Computers are easy to turn on.
Computers are ready when you are. Computers are very responsive. Computers aren't into finding out how far you'll go to keep your account. Computers do everything you tell them to. Computers don't care about age differences.
