After he left Apple, among other things, he founded the company that brought the first programmable universal remote control to market, then founded a company to make wireless GPS tracking tags almost 20 years before Apple made airtags, then served on the boards of several tech companies including the one that made the Sidekick (company later sold to Microsoft), then was head tech guy at a flash memory company bought out by Sandisk- among a number of other lead engineering jobs.
When not continuing to do tech work he also helped found the Electronic Frontier Foundation, the Tech Museum, a bunch of education/philanthropy stuff, and also founded Silicon Valley Comic Con.
Also he's still technically on Apples payroll (never left) and still represents them at events and stuff.
I mean, it's not putting rockets in space I grant you... but what've all have you two done exactly?
Seriously, I had some issues with his specific criticism in this case too, but the folks pretending he's just some has-been who got lucky one time 35 years ago and has been useless since is... not a great look....nor reflective of reality.
BTW there's an actual thread dedicated to this specific topic folks might want to take further discussion:
