I think OP means that if you didn't remove the real spider webs (thus removing the spiders and damaging the ecosystem), you wouldn't have to use the fake stuff.
I was reading a book the other day, a science fiction book from 2002 (Kiln People), and the main character is a detective. At one point, he asks his house AI to call the law enforcement lieutenant at 2 am. His AI warns him that he will likely be sleeping and won't enjoy being woken. The mc insists, and the AI says ok, but I will have to negotiate with his house AI about the urgency of the matter.
Imagine that. Someone calls you at 2 am, and instead of you being woken by the ringing or not answering because the phone was on mute, the AI actually does something useful and tries to determine if the matter is important enough to wake you.
I found myself wide awake at 4:45, and instead of trying to wrestle back sleep, I went to take a walk at the beach! Yay for motivation! As a treat, I'm having breakfast at a nice place nearby. It's still 8 am, and I don't have any work meetings until 10, so it should be a nice day.
If a building collapses. You blame the people who built the walls and poured the concrete, or the ones who chose the materials and approved the project?
In any case, often programmers and engineers retain no rights to the software they worked on. So whoever profits from the software should also shoulder the blame.
You know, it looks like clocks drawn by dementia patients
