I agree about incentive (with a small asterisk that if you do decide to take off when you shouldn't, now you have two problems), but taking off isn't particularly easier.

Eg you have to stay on the runway, you have decisions to make about whether to reject takeoff (the asterisk I mentioned earlier), etc.

For a computer, I'd say it's 6 of one, half a dozen of the other. For runway equipment (ie ILS), it probably changes enough that you couldn't "just use ILS" for takeoff.

I did infra work for a team that was contributing to Airbus' ATTOL (automated taxi, takeoff, and landing) project a few years ago. They (the ATTOL folks, not the side I was on) did do an automated takeoff demo and it definitely wasn't simple.
