hot take: the third prong on the mains plug is overrated.

it's only there as safety.

ideally, electricity would kill no one.

but even if we removed all ground prongs and holes from all mains plugs and connectors today, it wouldn't kill all that many people.

light bulbs don't have grounding. they work fine.

the ground prong is designed for the sort of electrical apparatus where the chassis is made of metal and some wire or the other might accidentally touch the chassis.

it's not all that useful in a computer, for example. i mean, if you have a habit of touching the PSU of your gaming rig, sure, maybe, in the unlikely event...

you can mostly get away with no ground wire. i'm prepared to get into an argument about this.

relevant information: i understand Ohm's law.
