The two brand spanking new 2019 "low end" models of the MacBook Pro 13" don't even offer the 32 GB option, and the MacBook Air doesn't allow for 32 either. So those machines will be obsolete in three to five years? Very unlikely given the use history of past models of these machines. My "low end" mid-2012 MacBook Pro 13" has had 16GB since 2013, and I still don't need that much seven years later.
Outside of esoteric professional applications, I've seen no comment here that tells me that a machine bought for normal or average or even above average consumer use will require 32 GB of RAM within the next 5+ years. All claims made here so far in this direction (get as much RAM as you can possibly afford!) are not, as far as I can see, backed up by real world examples.
Me, I don't need to hand Tim Cook hundreds of extra dollars for no good reason.
^^folks, this is what a educated consumer looks like.
