No, they don't.
They yet again show that you can get incredible speed out of pristine copper over incredibly short distance with no interference. This isn't new or shiny or breathtaking. They've been getting incredibly high speeds out of uselessly short cable distances for years.
No one has ever shown anything like that kind of speed on real world copper, even newly installed real world copper, let alone the crap that's in the ground.
I've given up on having a land line because the copper in my neighborhood is so bad that you couldn't actually hear people. How am I going to go with FTTN next year? You reckon I'll get XG.Fast speeds? Do you reckon that the government is actually going to go out to every single node and upgrade it to G.Fast, let alone XG.Fast? Under FTTP you replace the units in the exchange and your home router and you're done.
