The off-topic mentioning of graphics programming was because I tend to type as I think, then make corrections, and as I re-read it now the paragraph isn't great.

For what it's worth, English isn't my native language, and you'll have to take my word for it that no chat bots were used in generating any of the responses I've made in this thread. The fact that people are already uncertain about who's a human and who's not is worrisome.
