“Like a lot of others, I got my hands on a Sinclair Spectrum back in the—it must have been in the '80s, wasn't it? I remember a friend and I wrote software for that. We built some drawing program, sort of a CAD program back in the early '80s. We sold that in newspaper ads. I can't say that we made a lot of money, but that was the first piece of software that we sold and got into software and studied computer science at University. Did my Ph.D. in computer science, and never looked back.”
