There is something critical about usability, location of controls and feel, that's why buttons, switches and dials have been our friends for so long. An LCD as many mentioned have none of these though they compensate in terms of how much functionality can be crammed into them, but, at the cost of UI/UX. On the other hand buttons or physical controls fail more often than LCDs. Also muscle memory. When using an LCD one has to look at it whereas with buttons it takes a bit of learning at the beginning and after a short time then fingers go right on the spot without even looking or sometimes touching.. LCDs have multiple states so the location is not fixed. Muscle memory is not working very well in this case Hope we can learn something from the past and innovate more. As an anecdote, about 10 years a go I was interested into digital instruments (VSTs and such). After a few years I switched to real gear out of curiosity and was amazed at how much easier the UI/UX was and how well some things were thought out. I wanted to do something and my fingers would jump on the right buttons without even thinking. I surprised myself with this. This is very critical in some situations. Creativity can be hampered by something that steals your attention, even a few glimpses start adding up.. Same thing goes with safety.
