You clearly didn't catch the crux of his point - millions of people fly in passenger jets every day at Everest's elevation. All you'd need to do is pressurize the gondola, and there'd be no need for acclimatization.
Oh yea, actually, I see now, my mistake.
It's not some trivial walk around the park just because it's not considered one of the hardest summits in the world.
As for whether or not the gondola would be a good thing, I guess that'd depend on a lot of feasibility studies and cost analysis (cost to the environment, to the local populations way of life, monetary costs).
