Human minds are not compilers, we’re capable of nuance. Being as pedantic as when you're programming is counter productive in human conversation.
Also, i dont want self driving cars. Not until all the social issues are resolved.
And “made out of recyclable plastic” is a thing, and it works.
What isnt recyclable are mixed plastics, ie consumer plastic. But industrial users (ie folks who have large quantities of the same thing so sorting is cheap) can and do recycle plastic.
Also, before I studied material science (and therefore became an “expert”), I had heard that plastics are difficult to recycle in the mass media - as a teenager in the 90s. The information was there in a digestible form, but most ppl ignored it because it was easier to pretend that we were doing something with our blue bins.
I have clear recollections in undergrad (not mtls science) of throwing plastic into the garbage and getting lectured about it. And lecturing back that recycled plastic isn't really a thing.
Its been known since Flory Higgins back in the 1940s, and DeGennes completed the understanding in the 70s: the crux of the problem is melted plastics dont mix.
If anything in the last few decades methods for recycling plastic have been investigated fairly successfully. But they’re either expensive (sort plastic, return to feedstock), or have image problems (burn in thermal plants, turn into diesel).
