In this context the word decline doesn’t mean what you believe.I’m completely aware that this is just a PR soundbite/stunt to say “we’re still doing stuff”.
But aside from the M1 (and arguably, some Apple headphones to replace Beats models); it’s hard to see any 2020 innovation.
I would argue that aside from the constant output of the chip design division (and incremental product updates); innovation at Apple has been on a decline for the past decade.
