Dell and Lenovo may limit mid-range laptops to 8GB DDR5 RAM in response to rising memory prices

While I am on a desktop, I am also happy that that I bought 64 GB of relatively high performance DDR4.
It looks like I will have to stay with my AM4 system for at least another 2-3 years. It works very well, the only thing that I am missing is an update to 5800X3D, which unfortunately is impossible to get for a fair price since it was a one-time run only it seems.
