> copper can barely support 10G and is terribly power hungry when it does that Mostly a side-effect of 10GBASE-T dating back to 2006 - and all the chips used by early 2020s prosumer devices therefore using pre-2010 technology. Definitely a technological dead end, though - I highly doubt we'll ever see 25GBASE-T hit the market!
