So are water heaters and we use those pretty confidently.
Pressure cookers get a bad reputation for safety from the times when they were basically a metal box with a tiny hole in it, but modern cookers have a lot of additional redundancies. Particularly modern ones with timers. It'd take a lot of work to get one of those to go catastrophically. It's more likely to get killed by lighting than by pressure cooker, at least in the US, and as far as I can tell from available stats, and most of the pressure cooker injuries the stats list are from people who got a contact or steam burn, not by explosions.
It's also interesting that people are often afraid of exploding pressure cookers when they think of them as pressure cookers, but you don't get as much anxiety from rice cookers (AKA pressure cooker - but small).
I'm curious about how expensive. My last electric pressure cooker was a more expensive model (and I sold it after years in working order), but the stovetop pressure cooker I have at home now was more expensive than the entry-level Instant Pot branded electric cookers.
