i just can't leave it to post a comment as one similar of tpu user made me laugh: why is this wifi7 being pushed so hard?

In general or are you saying we're pushing it too hard here at TPU?

In general because the companies that sell WiFi hardware wants you to buy their new, shiny, fastest ever toy that you may or may not benefit from.
There are some benefits of WiFi 7 if you want to push a lot of data over the airwaves, such as MLO which allows the use of all three bands concurrently as a single wide data stream, but it obviously has limitations like the range of the 6 GHz bands. Most of the WiFi 7 features are of more use to corporate installations or for public WiFi rather than home users though.

I don't think we've been posting excessive news about it and this one is kind of important as it means that the standard is finally ratified and things should largely be interoperable, even if they never fully are when it comes to WiFi, since there are always some weird issues between different manufacturers of WiFi hardware. Mostly because someone figured out a "better" way of doing things...

The comment of an user caught my eye and made me laugh as such i felt a need to clone it.

Well it's new tech, and this is a tech related site so...yeah.

4k QAM probably only has mere inches of usable length. That's equivalent to... 12-bits per timeslot (much like how TLC is 3-bits per cell, QAM is a technique for stuffing more-and-more information into the same radio signal).

But yeah, 4k QAM is absurd. There's no way that's going to be used except in the cleanest and closest of transmission distances. Still, that's the kind of environment that same-room VR / broadcasting of wireless video requires. So there's practical applications here. Just don't be stupid and think that all of these specs apply to your router on the other side of your house blocked by 5 walls.

As I wrote, MLO is the only somewhat interesting addition, if it works as well as advertised. The rest are more fringe case improvements in a home environment.
The non-contiguous channels might be useful in some scenarios for a few consumers as well, if they can figure out how to use it.
4K QAM is also a bit of a marketing ploy, since it's a move from 10- to 12-bit per symbol, hence the 20% increase in performance and not a for fold increase, which 4096 vs 1024 sounds like.
Oh, latency is said to be vastly improve as well, but that's only if MLO is used, so again, let's see some real tests.
Other things like up to 16 spatial streams will never end up in consumer hardware.
