I think this video is a good example, because Max actually showed moving between different windows, open files, etc. It was not only export times - it was moving around the system. If your workflow resembles what he's doing - it is informative.
Now, he might not be a tech expert, but what he's showing is indicative of real world performance, and you can draw your own conclusions. So, don't listen to his opinions, look at what he's doing and decide.
For me, it was very similar to what I did: my current MBP has 16Gb RAM and I opened a lot of stuff to test it out (I mentioned it several times, but in short: a large 3D file, a bunch of large Photoshop files, a bunch of apps) and I used my computer normally - I did not notice any slowdowns. Same as in that video. And yes there was swap, in fact, I had like a 10Gb swap file and things were instant.
Of course. Why wouldn't you? If the whole computer was free, I would pick up 5 of them. Doesn't mean I need 5. ?
I think for me the additional RAM is not worth the additional price and wait times, but it's definitely better to have 32 than 16. Is it worth the cost? That's a different question.
Look, not everyone can justify the extra cost. Especially taking into account that prices are different. In my country, the upgrade is 530 euros - which is more than $600! In most of Europe it's $500+. So, random claims like "you need 32Gb if you open big PDF documents and browser tabs" might get some people to seriously overspend and others, who can't, to feel like they bought a slow computer that barely has a few years of life in it ?
This was the reason for this whole post. So, of course, if you have the money for it and feel like it - by all means get whatever you want. A 64Gb RAM computer *is* better than a 16Gb RAM computer. No doubt about it. But 8Tb SSDs are also better than 1Tb SSDs, so why not go around and advise people to future-proof (file sizes are growing!!!!) and buy a $6000 laptop?
Also, just to mention it here: we (this forum) had this exact discussion in 2016 when 16Gb was the only option on a MBP. And the comments were like "16Gb may be enough today, but it's a bare minimum and in a few years it will not be enough".
