There's truth to this but I still configured mine with 24GB/1TB.
For the apps YouTubers routinely demonstrate, exporting out 50 RAW images or a video, then 24GB RAM will be of little benefit. But clearly there are situations that justify 32GB, 64GB, or even more RAM. It depends on your use case and I definitely use my laptop differently than a typical YouTuber.
In addition to photo and video editing, I'll also do some mobile app development, run some Docker containers, and a Win11 VM occasionally. On my previous M1 MBA, 16GB/512GB was great for 2.5 years but the memory pressure was often in the yellow. While the M1 MBA was a great performer, I've opted to beef up the MBA 15 with some additional breathing room for the next few years.
Some will say I should go with a MBP at this price point but, no, that's not what I want. I already returned a MBP 16 and MBP 14. The MBA 15 is the keeper for me.
