at least it's short enough that it will only reach two plugs on the same panel, thereby guaranteeing that the first things that blow are breakers.

Even better:

i guess if you're got a bad breaker on your panel, you can load 2 circuits on one breaker with that thing, at least until the hardware store opens. you still get overcurrent protection.... but a very unlikely thing to need

The lovely suicide cord.

Worth mentioning that it is plenty safe...if used appropriately (for attaching a generator to a house that doesn't have an inlet).

It's when it's not used appropriately that's a problem. And it's very easy to not use it appropriately.

I don’t get what you were supposed to do with a plug and an adapter.

Those of us that remember our grandparents getting away with it are a product of survival bias.

USB-C is kinda sorta hermaphroditic.

Here's a handy reference: everything downstream of a plug socket is electronics, everything upstream of a plug socket is electrical.

Sincerely, an electronics engineer that works in the electrical field.

USB-C is specifically designed so it can swap between different modes safely by way of devices being able to communicate what they need from a plug via dedicated pins in the socket. So yeah, you can have USB-C male/male cables and it's going to be safe as long as you use it with compatible devices.

Pfisterer HV terminations are male to male. They also have big butt plugs for when they're not in use. Kinky Germans.

Bc when you plug something into the socket wrong, it always causes a full nuclear explosion! Yeesh, how did you not know this already...? (/s)

Electricians don't deal with HDMI or C cables, that's probably an electronics engineer job or IT

The better solution is getting a sparkie to install a male socket (with protective cover) for power inlet if you're anticipating needing a genset on any regular basis. While they're at it get them to also install an isolating switch so you can easily avoid backfeeding power into the grid while keeping the house powered.

You don't. You need an Interconnect and an "Inlet" port. You could use a male-to-male, but they're illegal and dangerous to the line workers.
