"It remains indirect, a defining characteristic of the second wave. Indirect inputs are powerful and lend themselves to muscle memory with practice" It's not indirectness that lends itself to muscle memory but rather staticness. To illustrate this, consider a keyboard that randomly switched between Dvorak and QWERTY. This keyboard would not lend itself to muscle memory at all, despite being as indirect as a normal keyboard. I think the touchbar could be beneficial in the muscle memory sense if it remains static within an application. At that point it simply becomes a more easily looked up version of Fn key shortcuts (but with potentially poorer tactile feel).
