As for Huxley, i was shocked by his approach and it made me think, but i do not know how much i agree. The Greek word for Human actually means 'the one who looks up' so i always assumed this is our natural course, becoming better. Then again, who knows? We can only guess, or at best pick a theory and live with it even though we will never know if we are in the right.
That sort of teleology (kind of a pre-determined course of history from humble beginnings to supposed epic finals) is also present in other belief systems. But, on the other hand, energy is not created nor destroyed, just transformed, so what we gain in some area, we lose in another. It happens with the usual economic concepts of "production" (mere transformation in fact) "growth", that have many hidden costs in ecological destruction and piles of residues, and it happens also with civilization, whose hidden costs are the need to submit to a larger and more complex social structure, where, even if we are treated as individuals, our individual expression is highly canalized and our social bonds hijacked by higher structures that are not nor probably can be fully participated by us.
I am often a nostalgic of the good old times at the East African savannah - but guess it's just because I've watched too many Serengeti documentaries. In any case, I know that humans have evolved for warm climates and daily exercise and hence probably crossing the tropics was a bad idea and so was assuming a sedentary lifestyle. One the other hand it is more comfortable once we have the sufficient devices, like heating and armchairs and very specially bathrooms and washing machines (that among the Mayans are thought as good not because they save work but because that way the young girls "don't waste all day chatting at the river", or so wrote Comandante Marcos in one of his books).
It's a complex balance and while we have achieved many things (I am particularly impressed by science and human rights), the path has been quite wavy, not straight at all, and everything has pros and cons.
Whatever the case the hive is not my ideal of human life, though it may work for robots or other species. I have said sometimes that I identify with Cadugan because of his misanthropy, rather than with the great concentrations of men, elves or orcs. I'd much like a quieter and simpler life, even if also get many benefits from this way of life, specially loads of general knowledge and some fun.
