What an obvious realization that I hadn't thought about, lol. I guess I could wait, but I am thinking of pushing him (lol) to developing interests for possible occupations that I know that can be reliably done independently where verbal expression of language is not primarily essential, but not manual labor. I can wait too and see if he bites or drop hints to see whether he develops slow interest.
In terms of occupations, who knows what programming will be like in fifteen years? In 2002, most people would not have expected pair programming and two pizza teams or Github's social coding to be mainstream methodologies.
Writing a Z80 assembler space-invaders game for an MZ-80K then ... and 10 years of school and then AI+CS honours and then a MSc in theoretical CS and then 20 years of banking and Y2K type nonsense etc etc ... and now I'm writing code for something of about the same power as that Z80 again, though developing with nice compilers and GB of storage on SSDs rather than kB cassette tapes so can get rather more useful loc working.
