why is 32gb such an unpopular upgrade?

Looking at buying a Macbook pro 2021 16,2" or possibly waiting for the 2023 version. Everything is clear to me but one detail: why is the 32gb internal memory option so unpopular? I mean like I get it, it's expensive to pay for, but you're already getting a VERY expensive machine that you're likely going to hold on to for maybe 6-8 years, and you're fine with having just 16gb? How would that be enough in a few years even when every **** app turns into electron and using hundreds of mb's?

Am I missing something? Will 16gb be just fine and I'm just overestimating what will be needed a few years from now or what?
