As soon as you have to buy something that takes up physical space, the "skills", or maybe better put the "mindset", becomes quite different. I don't think I can explain it very well. In principle someone who can understand a flow diagram (which is, to only mildly exaggerate, all a circuit diagram is) and master the complexity of getting a web application published online should be able to do what you did with the $3.50 board. They almost certainly could do everything in a short amount of time at a workshop with all the hardware provided and a printout of instructions. But once they're home, without a similar set of instructions for "buy this here, do this, do that, to accomplish this" it's unlikely you're going to see much robotic/smart-home creativity even after a workshop. Meanwhile unlimited complexity and creation can be had in the web app realm without having to leave the comfort of your keyboard, or even having to buy anything.

I just remembered this post which I think helps better capture some of what I'm talking about: https://plusbryan.com/its-just-wood But I think there's something else besides avoiding things that are mysterious. I think it has something to do with the physicality of the thing. At least something else is needed to understand the weird reluctance with working with hardware that a lot of software-only people have, who differently from the general public (who can't even use their computers) are sharp enough to battle with mind blowing complexity and solving mysteries of bugs or how new languages or APIs work every day behind their screens.
