|The operative word in the question is "you". An electronics engineer, a nuclear scientist, a theoretical physicist , an inventor, an astrologer-ly-these people have the opportunities to work directly with the tools of present technology, and they become aware of the awesome new practical applications that technology makes available. More importantly, these people function at technological levels so advanced, they become attuned to METAphysical vistas undreamt of before technology began expanding nd challenging (or destroying) the frontiers of knowledge in every field. So, yes, I would think for this elite group we could see opportunities for them to literally "expand their minds to greater things." In his later work, Einstein sounds like a religious mystic--and Stephen Hawkings' new work clearly indicated a mind vastly expanded from a decade ago.
These seminal thinkers, however, are leading-edge people. In many cases they are MAKING technology as much as they are reacting to it and thinking about it . But what about you and me? Is technology "expanding our minds"? I would say a resounding NO! Einstein and Hawkings et al are deeply concerned about how and why technology works. Where it has failed, and why?. Where it enjoys special success, and why. They must answer those questions so that they can work on new, expanded possibilities.
So, again, what about ordinary people--why do I suggest that technology does NOT expand our horizons?. Here, we must pause and remind ourselves that the question is whether technology expands our MINDS. It does not, for a very simple reason: for (probably) 95% of the population, the impact of technology on their lives is 100% FUNCTIONAL. My 14-year-old granddaughter can text with her thumbs faster than most adults can type, bur she knows nothing about how data moves from A to B. She will post 17 photos t her life, enables her too--all within 5 minutes. But she knows nothing about the technology that makes that happen--but the scary part is that she has no curiosity about it either.
I say "scary"--showing my age, eh? Why is it scary? Technology manages all the functions of her life. Along the way, there is a truly scary possibility her freedom of thought about how things work will transfer into a lack of curiosity about how things ARE, which could lead to automaton acceptance of whatever IS.
