Unfortunately is not just laziness. Working days are much longer now than they used to be. At my outfit 12 hour 4 sector days with 30 minute turn arounds are the order of the day. AT the best of times you are knackered and keeping the automatics is sometimes a way to keep workload (and fatigue) down.
I personally do at least one full raw data, manual thrust approach every few days but I have to admit that after one of those I am more tired.
Fatigue and automation dependency feed of each other
