This is old trope, and wrong. Small reminder that 100% of takeoffs and a vast majority of landings are flown by hand. That "1% of the total flight time" may be hand-flying the plane (ie, hands on stick and throttle), but all the flying that you're discounting in your 99% is still something that the pilot needs to handle. They need to manage the automation, the FMS, ATC, etc.

Patrick Smith (ask the pilot) has a number of good criticisms [0][1] of this "1%" trope.
