Well, while some would be quick to point out the lack of a desktop equivalence to Touch Bar and Touch ID, I see it differently. We haven't gotten a keyboard with those features because of two things:
1. Bluetooth is not going to work. Too slow and latency too high. You'd have to have the thing plugged in all the time, so technology is not quite there yet for Apple to create a wireless Touch Bar keyboard. Some may be okay with having the thing plugged in but Apple has had wireless keyboards for a long time now, so it makes no sense to introduce a new keyboard that requires you to plug it in, especially when Apple themselves is moving towards wireless for a lot of other things.
2. Would you buy a Touch Bar wireless keyboard if it was $250 or would you rather buy an iPad/iPod Touch instead? Speaking strictly as a consumer? And seriously, the million dollar question, even, is: would you buy a Touch Bar wireless keyboard that has butterfly key mechanism? For more than $200? I don't think anyone on this board will answer "yes" to that question at all. So there you go.
I too do not use the Touch Bar at all and I don't really see the point to it, but I doubt Apple is just going to drop it considering they have included the Touch Bar in 4 generations of their MacBook Pro (2016 to 2019) now. If the 2019 or 2018 MacBook Pro dropped it, then so be it. But even the 2019 MacBook Pro has it. So it's here to stay.
I think what the future will be for Apple is going to be very different from what most doomsayers are predicting. I think they will either:
a. Continue with the Touch Bar, try to find some kind of extra functionality for it, and add it into more of their computers. Also slowly raising the base price for everything because... T2 and Touch Bar costs extra. Honestly, they seem to be headed in this direction already.
b. Expand the Touch Bar and essentially turn it into an extra display, much like what Intel, ASUS, Lenovo and many other manufacturers are trying to do. Seems pretty unlike Apple to follow someone else's lead, but... hey, it can happen.
Because honestly, they have no other choice.
Or, if they even want to drop it, then the solution has already presented itself: they'll have to repeat what they did with the trash can Mac Pro: stop updating the MacBook Pro for years, and then suddenly come out with a new radical design (read: cheese grater) that doesn't include butterfly keys or Touch Bar. It'll have everything you guys have ever asked for, the CPU, RAM, and even GPU will be modular and switchable (albeit with proprietary connectors), it'll also have thicker profile with more room for airflow, have a billion tiny fans to prevent it from ever throttling down due to thermals, and it'll sport a 8K ultra retina XXXDR display with over 9000 nits of brightness. It'll also cost like... 3x more for the base model.
But hey, it's basically what you guys are asking for.
