I'm not expecting much considering the only response you could muster to my last post was a "haha" reaction, and that you are calling a physical electrical connection "dodgy" in comparison to a connection that relies on radio transmission, but I will try one last time.
First of all, it will be years before you can buy an actual WiFi 7 device for your home or office, the final revision of the standard isn't even expected until 2024. For the sake of argument let us assume that it works as advertised, which is far from a reasonable assumption. (On the other hand 10 Gigabit Ethernet is of course a technology that is already mature, possible to buy now and relatively affordable.)
While WiFi 7 very well may support a theoretical top data rate of ~46 Gbps you will never ever see data rates approaching this in any realistic scenario. Judging by implementation of WiFi 6 (Apple hasn't even moved to WiFi 6e yet) where clients are STILL restricted to dual-stream (2x2) my guess is that the 16 spatial streams promised by WiFi 7 will take a decade to materialize in mainstream products, if it ever does. Besides this, the issues of noise, interference, congestion and signal-blocking do not go away with WiFi 7, and these all reduce the practically achievable data rate further, often in inconsistent and unpredictable ways.
WiFi 7 is still half-duplex, whereas Ethernet is full-duplex. For wifi you will only have data moving in one direction at once. This does not change with WiFi 7. Wifi also has huge overhead compared to Ethernet, this will not change with WiFi 7 either.
Also, as far as I can tell, WiFi 7 will still share the top data rate between all the devices on the network, unlike Ethernet where each device connected to the switch can theoretically achieve the top data rate simultaneously. This means that regardless of how well WiFi 7 works in practice offloading devices that frequently use high data rates to the wired network will leave more capacity for the devices on wifi.
And once again, perhaps the most important aspect for me personally, LATENCY. WiFi 7 promises improvements, but it will never be able to beat the consistency and reliability of a wired connection. I can get ping responses hovering around 2 ms from some close Internet destinations (and less than that for my ISP's DNS even when running through a locally wired $25 pi-hole) connected to my router through an Ethernet switch. Reaching anything, even on my local network, is at least double that over wifi, and I have really good wifi.
