John Larkin doesn't seem to 'design" anything. He throws together the 
stuff he sells like every other tinkerer.

And rip off. John won't discuss anything - he doesn't seem to know how.

"Gated"? If you are depressed you won't design anything, but there are 
lots of different motivations for slinging stuff together and getting it 
right. If production ends up with something they can put together and 
the sales team ends up with something they can sell, the business of 
motivating the designers can be left to them.

Since the salesmen mostly want what they have already got - but smaller, 
faster and cheaper, they aren't really to be trusted with the job.

One of my bigger and more interesting projects got messed up because the 
boss, who also sold the product, was intent on claiming a 10psec timing 
granularity for the timing system in a machine whose narrowest pulse was 
500psec wide (we had hopes of getting that down to 100psec, but 10psec 
was a decade or so away). 100K ECL limited us to no better than 20psec, 
and ECLinPS was not around at that stage, so we bought into Gigabit 
Logic's GaAs parts - the project crashed shortly before Gigabit realised 
that they were never going to the yield high enough to make money.

It wasn't the only problem his unrealistic ambitions created.

They'd have to import talent from the pyschology department to attend to 
that.

https://en.wikipedia.org/wiki/John_Morton_(cognitive_scientist)

wrote a neat paper on human factors in design, but he an I could never 
work out which one was the one I'd read and liked.

That may have been what John Larkin saw in it.
