Landing is almost never done by autopilot. Approach is. When the runway is in sight Pilot Flying has to take over from the autopilot, and gently put the wheels on the ground. Computers are still not very good at it, especially not when there is slightest deviation from the norm (i.e. crosswind).

Autoland is very rare and is either used in ideal conditions or in terrible conditions (but then both aircraft and airport AND flight crew have to be rated to Cat IIIc standard - extremely rare occurrence).
