I feel limited by the latency AND bandwidth of wifi.
Latency interferes with use cases like wireless video streaming which is nice for things like Steam Decks or VR. We’re not even close to being able to decode even gigabit bitrates using hardware decoders though, so bandwidth isn’t important here. A nice coincidence is that Wifi7 coincided with the release of hardware av1 encoders/decoders, so I think we're going to see these SOCs that support both, and I think that's going to marginally improve the viability of computing remotely from the edge (Cloud gaming) or home servers (steam link) and cause those to be used more heavily.
Bandwidth interferes with large sequential file transfers, and WANs are starting to have more bandwidth than wifi, so this is starting to cramp things like large downloads of movie content or .iso’s or cloud backups. It also bottlenecks 2.5gbe LANs which are economical given they run on cat5e networks.
I think wifi7 is going to explode as ISPs bundle wifi7 modems with their higher bandwidth plans, so it’s going to be pushed because the ISPs need it more than because most customers need it. I only expect certain pros, gamers, and large scale commercial installers to invest in wifi7 themselves.

Even if your WiFi supports 1Gbit most of the time, tcp will throttle back to slow start (IIRC - the linear one) upon packet loss. And time to recovery depends on RTT. When I measure I always get inconsistent results on WiFi, whereas ethernet+fiber is butter smooth.
