10g is going to remain sufficient for office use for a long time.
Ultra Ethernet will be primarily for cluster/AI/Super computing, trading, server, and backplane scenarios where high speed low-latency throughput turns into money or bang for your buck.
Debbie in accounting will practically never need more than 10g networking to do her job.

And 640K of RAM ought to be enough for anyone. Who knows, perhaps in 2050 Edward will be mailing Debbie iterations of their 500GB AI fraud model for local inference?
The question isn't if 10G will need to be replaced with something better, but when.
Unless there are sea changes in the global infrastructure of computing in the next 25 years, that 500gb AI fraud model would be hosted on a server and made available to debbie through a web connection.
Further, almost every person on an internal network still uses 1g, which has been going strong for 25 years so far and will likely only cease being the standard when it's no longer economical for manufacturers to produce 1g hardware.
