I like the statement from Boeing's FCOM 1, saying:
Quote" Pilots must be aware that consistent use and reliance on automation levels III and IV throughout the flight regime will degrade basic flying skills. Therefore, pilots must continue to maintain proficiency by using all levels of automation on a regular basis." It looks like basics of flying any kind of airplane are not followed.
Also I believe, if pilots have face mask (required during Covid-19) while flying, it should be looked into for fatigue.
