Really super bad idea to use a Power strip when you don’t have grounding. That’s a lot of competing forces going on and you could easily screw up.
Run a few grounding wires in key areas. Peace of mind.
You’ll never get a clear answer on this one. Maybe talk to an electrician.
Don’t get cheap on things like this.
Maybe The world doesn’t need grounding at the outlets, but maybe someone thought this was a good idea and maybe it was a good idea after all.
Oh and without grounding it can lead to electrical shock for someone using electricity like an appliance or something. So basically every time you're using an appliance you risk dying from electrical shock.
I can’t see the pics but when was last time you had electrical box upgrade?
