I agree,
The current M1 Air/Pro and Mac minis are aimed at the average consumer, the real pro M1 machines are coming at a later stage. For those these machines are aimed at, I am certain 90% are totally fine with 8GB of RAM. The amount of posts of people saying "I've send my 8GB back and got a 16GB instead" are increasing with the day, because of the odd advice to get as much RAM as possible. Just because, there is no such thing as too much RAM...
There is definitely a thing called "having too much RAM".
If your workload demands 8GB, everything above is basically useless. It's not like that extra RAM comes free of cost, its still $200 U.S. (or at least 230 euro in Europe). For those moments your computer does need some more RAM, swap will take care of it without noticeable hits on performance. The whole package including the SSD is so fast nowadays, without obsessively looking at the activity monitor, an average user won't even notice it. Also, the lifespan of SSD's have increased massively these days, it's not going to die because it swaps more often..
Look at your own situation, your own workload and decide if you need 8GB or 16GB. If you're looking at a forum like this to get your answer, you're most likely fine with 8GB. Users needing 16GB, or even more know it (enthusiasts in video/photo/music editing or virtualisation). FOMO is a real thing, and it costs unnecessary amounts of hard earned money. Easy to 'recommend' if it's not your own money.
In general:
8GB - Office work, video conferencing, entertainment, daily web browsing, casual video/photo/music editing.
16GB - Video/photo/music editing enthusiasts, virtualisation users (parallels/docker and such).
32GB and more - Professionals.
Lastly, stop obsessing over memory graphs and just enjoy your new MacBook.
