Earlier quoted context omitted.
A gondola ride to Everest would be awful. A quick ascent to that height would virtually guarantee some pretty awful side effects for most passengers. I certainly wouldn't want to be on it.
Millions of people ascend to the height of Everest's summit every day, extremely quickly. I imagine that such a purpose-built gondola would, like modern jets, have a pressurized cabin.
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).
