47Gbps in wifi terms is like living to 200 but in dog years. The real speed will probably not be much more than 1gbit which is a common fiber connection speed.

WiFi 6 with a 2023 macbook does not practically deliver 1gbit, even with zero other networks nearby and the macbook 3ft from the access point you'll get something like 700mbit. One factor is that Apple devices so far don't support 160 channel width, only up to 80. But even with a 160 channel you wouldn't make the advertised "5gbit" because that's the aggregated speed across all frequencies and streams, which cannot be combined.

What do you think happens when everyone can transmit packets an order of magnitude faster, even if they're not transmitting at the line rate of the link? Average channel utilization drops precipitously and the transmit rates improve in aggregate for everyone.

Not to mention governments are opening up 1200MHz of spectrum on the 6GHz band (Wi-Fi 6E and 7) which is helping in heavily congested areas on its own.

We have 2, 6, 8gbps internet lines widely available here in NZ. Current wifi was capped out long ago
