>>OK. Now you've refined your analogy to include a valley between the mountain you're on and the higher one on the other side - which is probably a better representation. And it will take a while to get to the same altitude on the higher mountain. But IF the higher mountain represents a better technology isn't it still worth repeating the climb ?

It's true that the symptoms of altitude sickness are initial light-headedness often followed by a massive headache :-}
OTOH hand the 'IF' is possibly not that big - someone obviously thought there was a need for a higher mountain......
