That's not how people use 10x (which I think is a silly article of marketing at best or a pretend metric people like to claim as some sort of totem of achievement), usually it means someone 10x more productive(???) than a supposed 1x software engineer. In that case if we applied the same make believe as we do with software, then sure a 10x electrical could exist, just think of what you think an avg electrical engineer does and 10x it, boom.
