Redstone blocks vs redstone torches, and their relative strengths/purposes. Torches on sides of normal blocks with signals entering the side of the block. Using normal blocks to prevent redstone signals from connecting (particularly when going up or down stepped inclines). Space requirements to allow a signal to drive a block and not just terminate the signal next to a block.
These are all game analogues of laying out P and N state semiconductors, or conducting signals from one area of a chip to another and maintaining their signal quality, when designing ICs. Granted, these processes are hugely automated by tooling, but someone has to know, learn and understand how the materials science works in order to develop those tools.
This is why I'm surprised I've not yet seen a VHDL/Verilog compiler for minecraft redstone. Converting a gate array and netlist into a minecraft world feels like a relatively simple challenge for anyone with the knowledge, but I guess it's too niche of a project? Or I'm just not looking hard enough for it.
Calm down, it's just a building game where it happens that you can learn quite a bit about logic. I'd trying to get my 5 y.o. niece into it, since I find it to be a much better game for children compared to those pointless freemium mobile games.
Minecraft is fantastic for how simple it looks on the surface.
I guess my bias is that I played Garry's Mod with the Wiremod addon before Minecraft was even a thing, and it personally taught me a lot more about programming and logic than Minecraft ever could.
