Not to mention tolerance/fidelity. One print can be completely off from another due to random shit. If you’re trying to make parts that are consistently the same, you won’t beat the methods you described.
These people think everything is just magic. Add in their arrogance and you get hot takes featured in the OP. “lol stupid machinists why u don’t just push printer button? I could do ur job from my house. U are unskilled labor.”
Tbh 3d prints have high precision compared to other manufacturing methods. I think the biggest problem is some production methods make the material stronger. For example: permenant die casting and bulk metal forming. There is a limit to how strong you can make stuff by just changing the metalurgy. Another example: every bolt used in aviation must have its thread formed by thread rolling. They can not be made with chip removal methods like cnc lathes. Most bolts you see will already fit this criteria but bigger bolts might be made with lathes
