There's nothing which specifically stops you from having wormholes that don't violate relativity but do allow you to bypass annoying things like solid matter, but stabilizing them is something you also need negative energy to do.

Replacing all radio communications with point to point lasers via wormhole-on-a-chip devices would be a heck of a communications revolution (probably also an answer to the Fermi paradox).

I'm curious, why is that? Because the way I understood the Fermi paradox was that highly advanced civilizations should be visible from their energy requirements alone (e.g. via Dyson Swarms), not specifically in the way they communicate.

Radio waves wise, it would explain why SETI hear's nothing: the radio age would have lasted about 100 years before vanishing completely.

The assumption that ET communicates via radio waves has always seemed unusually anthropocentric compared to the rest of SETI attitudes.

If it’s not sending lasers through wormholes, it will be something else – but it seems the height of arrogance to assume that an advanced civilization would communicate via radio waves just due to our own familiarity with them.

You don’t see this elsewhere – SETI is always keen to downplay “little gray men” (they might not even take physical form! Maybe we can’t conceive of them!) or “carbon based lifeforms” (maybe they’re made of silica!). But for some reason there’s less questioning of any assumptions about their communications media. I wonder if this is due to SETI betting the bank on radio waves.

I don't think it would stop radio receivers from existing especially for astronomy.

Depends on how easy it is to project a wormhole endpoint elsewhere in the universe. If it can be done at >= C then sensitive radio receivers don't have much value.
