That's not a guarantee of anything.
For example, the BOSS Katana line of digital amplifiers has physical knobs. Of course, the knobs are digital rotary encoders. But do they have a display like most? No. So you have no idea of what you dialed in at a glance. It's easier to connect your phone through the USB port to the amplifier and manipulate everything through the app. It's appalling.

A million times this, also for safety concerns.
The folks at Space-X are not idiots, and they put shiny touch screens in the Crew Dragon spacecraft also for the press to "ooooh! Look at that, ...just like our cellphones!", but all important controls are also behind real physical buttons and joysticks. A touch screen looks amazing and so futuristic, until the moment something hits it in the wrong spot and they lose all instrumentation and controls in one shot. For important stuff I'll always take traditional rugged controls over touch screens.
Not true. If you examine sci-fi movies from the 1960s onwards, you'll learn that the most futuristic-looking interfaces have the most buttons and physical affordances. Touchscreens were never regarded as futuristic, and thus rarely depicted in sci-fi.

Not related to guitars, but I do a lot of off-roading and the multimedia system is only controlled by the big screen. In bumpy roads it's a trial and error operation to skip a song. Give me my previous/next physical buttons back.
