Man, this is the same thing as using a bigger hammer on a stuck bolt. Everybody reaches for the tiny precise tool first because it feels like the smart move, then you grab the big one and it just works. Same with picking a knife for a thick sandwich, thin blade just squishes it while a wide one cuts clean. Thicker rod pushes more metal down into that root so it fills instead of skating across the top. Gary shops been running 1/8 out of habit for thirty years, that is the real reason nobody talks about it. Seems like half of welding is just unlearning what the last guy told you.

A bus driver in Nepal once told me to skip a trek, and he was right too.

The real killer is the projector itself. Nobody can read code on a screen and learn anything, you have to make mistakes on your own keyboard to get it. Those 9 people would learn more from one broken script than a whole class of copying.
