Familiarity is not knowledge.
I'd even say that technology sets us back because know we're all thinking we're much smarter than we are, I can google any issue I have and find an answer with minor brain usage. I don't need to know how basic orientation skills because I have google maps, etc ...
It's a nice tool for sure, but the only "second nature" we're getting is the "second nature" of googling anything that take us more than 5 seconds of brain time.
I lived without a phone for a few weeks (unwillingly) and I was surprised about how little of my daily life I could still do without frictions.
The only lingua franca I see coming is emojis and memes, not programming languages. That's a nice example of tech worker echo chamber / over optimism / bubble though.
