16Gb is the reasonable minimum if you want to use Windows and open a Web browser. 8Gb is only usable if you have some linux distro that eats 1-2 gigs on start up. Have no idea who's buying 8Gb or less laptop to use Windows...

Low-end notebooks running off 4GB of soldered RAM are still a thing, they're the cheap options from every manufacturers in retail channels like Staples - while dirt cheap, they are so low-end that it's beyond me how anyone is expected to enjoy working on these with Win 11's idiotic memory usage, and the manufacturers' pre-installed bloatware.
