as an aside, someone with a technology 10,000 or a million years ahead of ours trying to “advance” us would be equivalent to us trying to teach a group of cavemen to manufacture a laptop PC with their existing technology.
the acquisition of knowledge and technology must occur in tandem and the advancement of both is necessarily an incremental process, that is, newer knowledge and technology has to be built on the older in an incremental fashion.
it’s pure fantasy for those who believe that a “super-advanced” civilization could land on Earth, wave their magic wand, and instantly transform us into them. Using the caveman analogy, the best they could do is probably advance us from stone tools to some type of simple copper ones by showing us a simple wood-fired copper smelting technique with easy-to-smelt copper ores.
Imagine Ben Franklin being handed a silicon chip in the midst of his electricity experiments.
It would be centuries before it’s capabilities were understood.
