Actually, insurance aside, I think we can look to the military to see future trends. Except for the armaments, most military technology eventually finds its way into civil aircraft. Think retractable gear, CS propellers, pressurisation, VHF R/T, gas turbines, metal alloys, GPS, digital avionics.
What replaced the R/T operator, then the navigator, then the flight engineer? Computers or computerised components. Same as what has (largely) replaced the military's reconaissance pilots.
As for CTA steps, the last light twin I flew was capable of warning me every time I approached CTA, either vertically or horizontally. That was a Diamond DA42. The CEO of Diamond is currently trying to raise interest in his company's next offering, a computerised emergency recovery device for the same twin. Some sort of GPS / AHRS computer coupled to fly-by-wire I believe.
It's coming. Just a question of whether we'll be retired when it does.
