There’s an interesting economic point to be made about the specialization of labor and the benefits that arise from that.

Just like it is more efficient to have a food system than to have everyone feed themselves from their backyard (if they have one), maybe someday people will realize that it will be more efficient to build things once and re-use.

Similarly, every argument for “AI makes it cheaper so we can do it now” falls apart under “AI also makes it cheaper to not do it”.
