year the brand name was first introduced.
It says so in the legend. Zoom has been a word for a long time but it now also means "participate in a (video) teleconference", which is a new meaning directly linked to the zoom software released in 2011. When a word became generic is usually very hard to pinpoint exactly (except for zoom that was 2020)
For heroin: I don't think there was heroin before the introduction of the heroin brand. Bayer literally invented the substance. (Wikipedia says it was invented 23 years earlier in Britain from morphine, but the inventer didn't do anything with it so it was reinvented later). It was also not a drug you take to get high, it was an over the counter cough suppressant; no needle or spoon or lighter involved. Wild times for sure...
Repeat after me:
"Current AI is not a knowledge tool. It MUST NOT be used to get information about any topic!"
If your child is learning Scottish history from AI, you failed as a teacher/parent. This isn't even about bias, just about what an AI model is. It's not even supposed to be correct, that's not what it is for. It is for appearing as correct as the things it has been trained on. And as long as there are two opinions in the training data, the AI will gladly make up a third.
