I'm not sure if we'll see >10G over twisted pair/CAT but I'm sure we'll definitely see 5G and 10G baseT become far cheaper with 2.5G the baseline (e.g standard on cheap things like raspberry pi).
Base level Mac studio is already 10G as standard and it's only $100 extra on a mac mini.
Long time until 10G per device isn't enough at home.
I also doubt above 10G will be seen at least on consumer grade hardware, but until we start seeing SFP+ or similar on consumer hardware (and not just enthusiast and server hardware) there is a realistic chance. But that is so far out in the future making predictions on it doesn't make sense.
