I bet you had to look at the iPad to type that though, and you are slower then on a physical keyboard. No one would type a 30 page document on a touch keyboard. Look at cars, some car companies, especially Volvo, and Tesla, have moved controls for temperature, air speed, volume, and radio stations to touch displays, meaning you have to take your eyes off the road to make your adjustment. At best this is poor ergonomics, at worst this is actually dangerous. A knob can be operated without taking the eyes off the road. In other areas touch devices are the better solution, especially those involving many complex operations. To stay with cars, touch screens are better suited for making adjustments to things like suspension settings, throttle response etc. It would take many, many buttons, in this case you just need a screen. Plus these functions are used infrequently.
Or take aviation, both Airbus, and Boeing have moved things like the controls for interior lighting to touch devices, so that every airline can set their own color to suit their corporate ID. But no one is even considering moving critical flight controls to touch devices. If an aircraft has a rapid decompression the pilots have roughly 20 seconds to respond, but since they will likely be momentarily blinded since the air is fogged up, and the blood vessels in their eyes have burst, you do not want them dabbing around on a touch screen, you want to give them a physical interface they can operate without seeing.
I can easily imagine a starship hundreds of years from now still using physical interfaces for critical functions.
