First job out of college was at the transportation system center m i t in cambridge. A lot of research went in that place, for example, of artificial intelligence and expert systems. After i left there, i went to b b n, both rannic and newman. It's really research and development; considered like a halfway house between industry and academia. I didn't have any specialty. I just liked learning and doing new, interesting things. And what does email mean? First of all, it came into existence back then when computers had eanly words.
