I designed a small circuit back in January. I ended up going with a PIC microcontroller because it was the only thing I could find that supported USB and was in-stock. I ordered enough parts to build four, from Digikey. Now, 6 months later, I want to build some more, and about half of the BOM is out of stock on Digikey. I was able to source most stuff on Mouser instead, but the switches I used weren't available anywhere and I had to go to a different manufacturer, driving the cost from $12 of switches per build to $18. Huge pain in the ass, but at least I was able to get it done. I feel for the people who designed around particular parts and are now starting at 2023 "in stock" dates.
