You're funny. I never know if you are serious or just yanking our chain.
Assuming you are serious, I think he might be referring to Adam Osborne, He created a "portable" commercial computer back in the early 1980s. I wouldn't exactly call it portable. I think it was about 25 pounds but he would brag that it would fit under an airline seat (well not today's airline seat.
The big failure was when he announced he was coming out with a new superior smaller portable. People stopped buying the existing one and it was one of the main reasons he went out of business. He came to our company looking for a position in the late 80s. Do you think we hired him? no. Let's hope Elon is smarter.
