Does Ethernet over twisted pair die with 40GBase-T?

I frequently try to field questions on /HomeNetworking from people about to install Ethernet wire in their homes who want to future-proof of know what they should install instead of CAT6a wire. I always recommend conduit, because we don't know what wire to use yet.

Based on the current standards we can get 40GBase-T on CAT8 cable for up to 30M, but there's no matching standard for 100GBase-T. Is this the fastest Ethernet over twisted pair wiring we are going to get? Ten years from now, will everything go to fiber for long-distance runs?
