Again, bugs are a completely other story. If you have a bad memory leak that is an issue that needs to be fixed. That's a straw-man argument, FYI. This discussion is around general RAM required for operating day to day with functional software. 8GB is pathetic on any new machine at the price point Apple charges. Sure, I have an 8GB RasberryPi that is great with 8GB and even 4GB, but it's a small embedded computer not meant to do much at the end of the day and costs less than $100. Come to think of it, it has 8GB RAM and costs less than $100 for the whole thing. For what Apple is charging, it should start at 16GB for even the base model. If you are consistently seeing red memory pressure on your system (and the software you are working with isn't bugged), You need more RAM. Period.
Just a note, the RaspberryPi 5 uses LPDDR4X-4267 SDRAM, which happens to be the same as the memory used with the M1. The newer Macs and all Pro versions use LPDDR5X, which does probably cost a couple dollars more, sure.
