Tech power users are still a niche in virtually every use case except maybe HN

Tech power users (and power users in general I would say) might have more money to throw at the problem. "Nicheness" isn't necessarily a bad thing if your niche is profitable. I heard somewhere that power-grid-scale transformers are have insanely long lead times so the industry most be pretty niche (when's the last time you needed one of those?) and yet I think we can all agree that the equipment is valuable and I bet those manufacturers are making bank.
