Dozens of users in our environment are using 8GB with zero issues. Most are on Teams all day long with multiple tabs/windows/browsers also open. I once did a test with an M1 with 8GB and had 100+ tabs open across three browsers (Brave, Chrome, Safari), 20 YouTube 4k streams playing, Excel and a huge spreadsheet (thousands of rows of data), and MS Teams running with a video call. Memory pressure was in the yellow and some swapping happened, but nothing that affected usability and certainly nothing most office workers would notice.
8GB is hardly a disgrace, the M1/M2 definitely seem to work very well with 8Gb. Years of actual data to back that up, so others can buy with confidence.
