Speaking of high tech-savviness demand: I haven’t the faintest idea what that even means. So the curve’s a lot steeper than you think.
For me, the computer’s a tool. I want it to work; I don’t want to have to build it. I didn’t build my tractors, either; or even forge my axeheads.
I have a large number of other things I need to learn in my life, including others which require continual update of knowledge. I do not have the time or brainspace to learn, in addition, enough of the underlying structure of computer software to get to the point at which the above sentence would make sense to me; and I’d have to do that first before being able to even try whatever it is that you’re talking about.
