The death of the PCIe expansion card

With the AM5 platform from AMD on the horizon, five major motherboard manufacturers have annonced their flagship motherboards with the X670E chipset. Some of them are having fun with this generation's multi-faceted step into five": AM5, PCIe Gen 5.0, DDR5, 5nm process, boost clocks over 5GHz, you catch the drift. But do you know what every single announced motherboard has fewer than five of? PCI Express (PCIe) slots.

Other than a GPU and the occasional WiFi card, I haven't really had any need for my expansion slots in a long time. I just don't know of anything useful. I doubt they'll actually go away any time soon though.
