3 things

1) I don’t disagree with the spirit of your argument

2) 3D printing has higher startup costs than code (you need to buy the damn printer)

3) YOU are making a distinction when it comes to vibe coding from non-tech people. The way these tools are being sold, the way investments are being made, is based on non-domain people developing domain specific taste.

This last part “reasonable” argument ends up serving as a bait and switch, shielding these investments. I might be wrong, but your comment doesn’t indicate that you believe the hype.
