I love cooking and use my Thermomix a lot. If you hadn’t heard about that amazing innovation, it's a kitchen robot… Well, it’s a magical super cooking machine. When designing the Thermomix, its designers took the approach of fail-safe instead of fail-fast. This is a smart choice in this case, but it has its drawbacks.
E.g. my machine tried to recover from a failure which sent it into an infinite recovery loop. I literally couldn’t pull out the food from the lid that was sealed shut. But normally, it’s one of the most reliable devices I own.
