Touche, a more or less decent pool robot cleaner is around 3k and doesn't last more than a few years without changing every part but the case itself. Ok I take it - it operates in somewhat "hostile" environment but the point still stands
It didn't need an LLM or deep learning to do its job because it would randomly crawl around so long that it was on. I don't understand adding complexity, fragility, or cost to a solved problem, but I guess there are enough people who engage in competitive conspicuous consumption to signal status.
