Does anyone have an actual answer to the question? I have someone I’m trying to convert to Grapheneos but who is also trying to run a business, making a simple “block unknown callers” not very tenable.

Apart from that, if “useless” people truly didn’t have a purpose, then why did nature make them in the first place?

This won’t work on this sort of person. Failure is a personal choice in their narrow world view.

Red, orange, yellow and green are all the same varient, but at different ripenesses. The others are different varients.

Mostly just a novelty. Throw in a bit more colour, if available.

Not sure I’ve seen an orange, white, brown or purple traffic light before!

That’s Greek and we have a pretty good understanding of them.

I think the person you’re replying to is referring to these odd little dodecahedrons that we keep finding in former Roman provinces, but for which we’ve found no documentation as to what they were for, if anything.
