It's the opposite: In the last decade networking connection speeds have plateaued. In the 90s we had 100M ethernet, in the 00's 1G ethernet, in the 2010's 10G ethernet, and it stuck there for a long time. We had much much less CPU cycles available per packet when 1G came, for example.

I don't think I have seen 10G ethernet network card in consumer grade hardware even recently. 10G is there in core infrastructure for a long time. But only until recently you see 2.5Gbps in endpoint devices. (Probably 2.5 makes more sense to a RJ45 head cable)

And also I don't think 10G routers/switchs ever use pure software based solution to handle the traffics. They are all hardware based or mixed solutions.

It's amazing that memory bandwidth / cpu speed / core counts grows so much that makes this even possible. But it still isn't a good idea.
