It definitely seems promising, but I admittedly need to spend more time deep-diving on it! Good idea for a future video.

I do think in general people underestimate the network effect and momentum that already exists with the Lightning Network so while anything is possible I suspect “supplant” is likely too strong even if Hedgehog proves technically superior, and it would be more likely to see some Hedgehog-like tech built in as a new BOLT eventually.
