@geerlingguy SBC market stopped being hobbyist, RPi is used for literally everything where you need a reliable small computer, and thus in high demand. Even without the NAND and DRAM market situation, I doubt RPi will ever be as cheap as they were before.
There are alternatives that are priced better but they often lack in software support, for professional use these aren't that viable, but a hobbyist with enough free time might work around that.
