Robots are great at carrying out well defined tasks in controlled environments, but they are still severely lacking in most of the skills that are valued in today's society (creativity, problem solving, teaching, influence, etc)

Although your argument is correct, your conclusion that 2048-bit messages are uncrackable is misleading. RSA claims that 1024-bit keys are likely to become crackable some time between 2006 and 2010 and that 2048-bit keys are sufficient until 2030.
