It really is a genuine mystery why mystery creates a sense of awe and why learning for many people leads to cynicism.
Maybe we are driven toward learning via an emotional mechanism that draws us to the unknown and gives it a "sparkle" or "allure" similar to how sex drive works. Once we learn that mechanism turns off, again similar to how the sexual allure lessens after orgasm.
It offers a heady sense of power and control, even though you intuitively know there's always a catch. If you want to be powerful like a genie, you have to learn to live in a lamp and do the bidding of whatever random a-hole figures out they have to rub it.
The unknown is glamorous, and indeed an old word for magical spells was glamour. The disenchantment that results from actually learning how the spells work is the revelation that nothing truly offers infinite power, not even magic.
Wisdom is the discovery that a world without magic, as much disillusionment as that might save people, is also a world without wonder.
Children would stop getting impressed by dinosaurs once we start cloning them and putting them everywhere. Any wonder that's ubiquitous is by definition no longer wondrous
Evolutionary imperative would be a very simple explanation. The Sentinelese [1] are probably the best example here. They are a group of people that "we" have tried to make contact with numerous times, including with the offering of gifts. The Sentinelese have responded by, for the most part, trying to kill the visitors and occasionally succeeding. But the most interesting thing about this people is how incredibly primitive they are in other ways. They literally have not yet learned how to make fire. Instead when a lightning bolt catches something on fire, they have been observed guarding and trying to keep the fire going for as long as possible. And they have no knowledge of agriculture either.
The point of this is that if at some point people were sufficiently awed or contented by discovered technology your society would start to reach a point where it would simply freeze in time. Instead this instinct we have to assimilate, absorb, bore, and repeat - to no end, is something that seems likely a factor in our (as of yet) never ending drive to develop, expand, and grow.
