Don't shoot the messenger; this stuff is already under development. There is an R44 test rig in existence demonstrating autonomous flying

The automotive industry already has a suite of car sensors measuring everything from speed and attitude to passenger occupancy and weight, mainly for safety systems, airbags, etc. The electronics are incredibly reliable, cheap, small, and lightweight. I watched a video about a Bell 505 in which the pilot entered the weights of his passengers into another Garmin; this can be done automatically.
For 2-3k, you can buy a DJI drone with 360-degree obstacle avoidance. Let one loose in a forest, and it's impressive to watch how it navigates its way through trees and branches, all in a cheap package. You can already plot a flight path on the ground on a mobile phone or tablet, upload it, and the drone will fly it; the drone's onboard obstacle avoidance ensures no crashes if you get it wrong.
Crystal Ball Time, the next systems for PPL, will offer an autopilot for flying at altitude and augmented pilot help for low-level flying, landing, etc. It's not really flying using piloting skills but rather similar to controlling a drone. The owner will nudge the cyclic in the direction they wish to go, and the onboard electronics will do all of the hard work.
I still believe the need for professional pilots will increase for commercial operations; Businesses will insist on having trained and certified meat sacs in control and command.
