What tripe.
Look at the speed tape on the big sheet of glass. See the pointer is in the big, bad, red & black bit and you know instantly that's not good.
Look at the pointer on the big round dial of yesterday and see that it's pointing at some arbitrary point. It might be bad, it might not be so bad. But you don't know until you compare it to the stall speed for the weight of the aircraft at the time. That is NOT something that is done as instantly as seeing the pointer in the amber (not so bad) or the red/black (bad) on glass.
It's all very well going on about maintaining hand flying skills etc and I agree with that. But suggesting that we revert back to old style instruments just because that's what they did 'back then' is just nonsense. Many of the modern instruments have been developed so that we can instantly ascertain the situation and the speed tape is certainly one of them.
IF the Asiana crew had looked at their speed tape they would have known the situation. They either didn't look or they obviously didn't do the correct thing to resolve the situation if they did look. The lack of A/T awareness was key in this lack of correction.
