Do you believe that robots and autonomous systems, keeping in mind that they will develop by leaps and bounds between now and whenever regular Mars trips are in full swing (say 15 years from now), will somehow not take a lot of the load?
On the other hand, the point of modernizing the UX is indeed to make things more accessible, but that is absolutely necessary if we are going to expand beyond Earth.
Ignoring the idea of a Mars colonization effort, even just a roundtrip to Mars is a several years long mission. You're going to want to simplify the 'routine' parts to allow the astronauts to focus on training for the unknowns.
