True - but multimedia folks can buy separate controls for their specific needs; (for example, I use a separate volume control knob; just to have a handy way to control volume; mainly because my external keyboard's volume buttons require fn-key which is annoying when I need to respond quickly to change volume or mute.

So the touch bar might be great for SOME purposes in multimedia, not for others; but a variety of VERY CHEAP peripherals are available for these purposes - no need for a one-size-fits-all integrated approach.
