Are you suggesting that Tim Cook was not involved in the development of the Apple Watch or AirPods?

When did I say that?

The point was about the meaningless of calling products ‘derivative’.

The Mac can hardly be called derivative. If you want to go that deep into that kind of logic, you're really reaching to the point that all things are "derivative" of basic physics and no one has ever done anything that's not "derivative".

It's pointless argument.

If you don’t think the Mac is derivative of the Lisa, which is derivative of the Xerox Alto, then I’m quite surprised.

Which was a derivative of ... which was a derivative of ... which was really all derivative of John von Neumann so what's the point of this ridiculous argument.
