Because the OP is just dehumanising some basic, primary stuff, it's like telling someone to not sh*t in public because in so doing it also casts a bad light on us, people who happen to be watching him because we just happen to share the same sidewalk.

I don't want to be part of a world where people invaded by AI psychosis have turned a basic human thing like gardening into this AI-monstrosity.

Let’s say they just set up some sensors and automation based on regular algorithms or something like Home Assistant, would that pass muster to you? As in ‘hey look at this, I hacked some plants!’? This is just going one step further. You’re free to not like AI (I’m reluctant myself) but this seems to me like someone bashing some stuff together for fun. In my opinion you’re overreacting.

People like you will complain when AI makes it unnecessary to use pesticides in farming. bUT mUh hUmaNizED FArmiNG?
