They are hiding out there sometimes - toss pot Captains who think that you can't be anywhere near as professional an aviator as them because you only have three stripes.
Wasn't so long ago I used to fly for years single pilot multi-IFR with no useable autopilot. Pretty sure I would have crashed had I kept two hands on the control column then. Hard to believe I used to tune radios and navaids, follow charts, change heading bugs, talk on the radio and look out the window etc without another pilot there to keep me safe. I find it a nuisance that I have to ask 'he/she who must be obeyed' to do all those things for me now. Surely it is not beyond any competent airline pilot (in either seat) to turn their own heading bug while hand-flying? Really?
Being able to comfortably fly the aircraft one-handed (even a widebody jet on a long-haul flight) shows you have the aircraft nicely trimmed and under control and probably have some capacity to spare...
I would welcome that on a flightdeck - not criticise it!
