This has nothing to do with what I was talking about.
a) in the context of the quotation, artificial beings who were accepted as having genuine emotions existed.
b) my statement was that "humans can still feel accomplishment even if robots make their work unnecessary." The only implementation of any relevance was the human one.
c) an accomplishment is defined by the obstacles you overcome to achieve it, so it does not need to be special. You, as a human, faced the challenge with more obstacles than a purpose-built machine.
That all being said, I'm detecting some really profound anti-AI chauvinism here. Subjectivity is about how evidence from your environment influences your thoughts and decisions; if a mind can process well-formed hypotheses and beliefs, then it can judge itself to have accomplished something. There are two problems with your last paragraph:
a) How do you, personally, know that everyone around you isn't lying to your face about what they believe? Claiming AI would be non-genuine because you can't "detect" anything more is no different. There would be debugging procedures both equivalent to, and much more powerful than, the fMRI we currently use to detect (what we think are) genuine emotions in humans.
b) It would be impossible to build an AI that behaved fully human without either copying a human template or understanding how it worked. If the human template is copied, then the new model has no appreciable difference; if the AI built from scratch, we'd know for certain how experiences would affect its decision-making.
That does not diminish the personal sense of accomplishment of the endeavour. There are plenty of inadvisable and dangerous recreational activities—parkour, skydiving, and deep-sea diving to name but a handful. Humans have undertaken hazardous physical challenges for sport since the dawn of time, and no amount of fretting over it will curtail that.
Challenges are defined by the limitations and risks you face them with. Whether or not you approve of people confronting particular ones because they are extremely dangerous really doesn't contribute anything at all to this conversation or affect the validity of the analogy.
In fact, Everest has been climbed by a helicopter (and it was unbelievably difficult and dangerous) and some really impressive music has been composed by what is far from a strong AI (even if it is relatively formulaic).
But neither of these two things have anything to do with my actual point.
Even in a hypothetical world where excellence itself is obviated by technology, or some race of superior beings, or even by mere changing tastes, the challenge itself still exists. Every time someone faces an obstacle it is a reflection on their own upbringing and personal history, and that is equally if not more important than the actual magnitude of (artistic) accomplishment. Even if—no, when—all you say about human standards of beauty fades, and there is nothing left remotely humanlike to judge subjective aesthetics, the achievements of those who lived and worked and created will not be diminished. Neither the sands of time nor the mountainous shoulders of giants yet unborn having any bearing upon this.
Everest was actually my original example, but I changed it because, although (as everyone else has now pointed out) while it's been done, you're right, it's incredibly dangerous and possibly even harder to do than climbing by hand. If this does not satisfy you, substitute some sort of high-atmosphere, highly manoeuvrable balloon or space craft. The general point remains: respect (especially in art) comes not just from what you do, but how you do it.
