Okay, a few things need to be straightened out:

This particular aircraft, a CRJ-200, cannot land itself at all. Additionally, no commercial aircraft have an automated takeoff feature as it is not necessary. Although most commercial aircraft have autopilots, the computers that control them must be programmed and constantly manipulated by the pilots.

These pilots did not fall asleep because they have little to do. Although aircraft have become more automated, the airspace they fly in has become more complex and congested. It could be argued that airline pilots have HIGHER workload than they did 40 years ago, when there was nearly no aircraft automation.

The reason these pilots possibly fell asleep is twofold: First off, they are working under FAA rest requirements that have not been changed in decades. Rest requirements for flight crew members are far less restrictive than those of truck drivers, or any other transportation workers. Additionally, these pilots fly for go! Airlines. A subsidiary of Mesa Air Group, which is notorious for labor abuse, not too mention unfair trade practices. A quick Google will tell a reader everything they need to know Mesa Air Group and their actions.
