Pilots still have a lot to do, they must monitor the radios, the weather, fuel, etc. Since plenty of accidents have been caused by not paying attention to these things, I don't think you can say that having more time to do them is a bad thing. If there is a lack of manual flying ability it is entirely due to culture and not the aircraft. Pilots can and do turn off the autopilot if they want to practice, and most landings are done manually because it is softer.
