> The new touchpad and touchbar could also be used on a new design which allows enough for a high-quality keyboard.

For sure, as noted I'm all for that. I don't think we need to move back to 2015 to accomplish that though.

I don't think anyone is saying there's no room for improvement but I would really like it if the requirement was that they fit a high-quality keyboard in even if it meant being 10% thicker. My home laptop is still a 2010 MBA because, even after almost a decade of heavy use, it still feels better than the brand new keyboards — that's completely ridiculous.

Well, unfortunately this will probably never be the case. I actually don't mind the new keyboard at all. It's not my favorite, but I actually would rather have the extra thinness than extra action, and believe it or not I prefer it over the 2015 macbook keys (overall I mostly use desktop keyboard though). And it seems the market is mostly in agreement.

High action keyboards will continue to be phased out by thinner devices and more touch. Many will lament it, but I don't see moving back.

The touch bar is not a selling point. I like my escape key!
