Rejoice! PCI Express 7.0 hits 'final draft' status enabling bandwidth that you probably won't notice on devices that won't appear for years

Call me back in 2035 when things are getting real.
I'm ok with this. Standards need to be developed years in advance for proper adoption. Without them, we can get weird arbitrary tech barriers... Like 640k RAM for example.
Ought to be enough for anybody.
I'm confused. Are we mad at hardware research and development as a concept now or is what's left of the tech press just stuck in permanent snark mode and just can't physically write any other way?
I mean, not every new standard is meant for home use primarily out of the gate and PCIe devices are backwards compatible with older standards, so... yay, people who need to build a very fast NAS will be able to chuck more, faster drives in there now. Good for them.

It feels like it
Well, I guess you can have more potent PCIe cards now, so you can add QSFP variants like QSFP256 or just multiple connections, without worrying about bandwidth.
That is, if that is actually used somewhere, currently we're stuck at 5.0, and servers usually are not meant to have connectivity added in, but rather to just have it (more cash for the manufacturer anyway).
We can’t get decent video cards hardly at all let alone something that would use this.
the advantage for pci-e generations isn't the gpu side, but SSD side(USB too). CPUs by design, have a limited amount of PCI-E lanes they can distribute. Modern SSD's primarily use 4x pci-e lanes, but if you have a generation newer, you can allocate half as many lanes to achieve the same speed.
Since at the moment, the value of even faster SSD's are useless, what ACTUALLY becomes off value is having multiple m.2 slots for expansion. for example, instead of having 1 m.2 running pci-e 4.0x4lanes, you can achieve the same speed at pci-e 5.0x2lanes, or pci-e 6.0x1lane. Using less lanes on m.2 slots means you can allocate more bandwidth to other components(more m.2, more USB ports, etc).
this for eaxmple was the reason why experimental gpus like the Asus Dual RTX 4060ti existed, as its a 8 lane gpu, which had an on board to use the other lanes as ssd storage on motherboards that supported bifurcation.
1 lane NVMe SSD.
Most modern GPUs barely even use the full 4.0 bandwith. Hell, even 3.0 is still enough in many many situations.
Have you considered that we could reduce the number of lanes available and fuck some of our customers?

This is why I'm still on a 3060 and will be for a few more years yet. There's no point to upgrading.
