I find it laughable that people are still believing that upgrading the RAM from 16GB to 32GB will make a significant difference to future proof you laptop for the majority of users, and to be honest is not based on fact and is misleading to other forum readers, at best it is your opinion. To be clear, yes some users would benefit from the RAM increase to 32GB but that would be based on their needs today. If you are frequently using professional grade apps that push the memory requirements, and every second counts in terms of your ability to generate income, then 32GB makes perfect sense.
My arguments is supported by data - There are numerous reviews that have done objective tests, some of which have already been linked on the forum that on the whole objectively conclude for the vast majority of users 32GB is wasting your money, and if you have additional money to spend it is better to spend it in other areas, for example increasing the amount of SSD storage, or moving from 14” to 16” for larger screen, better speakers and better thermal performance in terms of fan noise.
in addition I have been buying Mac Laptops since 2002 and generally replace every 3 to 5 years, I have never upgraded the RAM back in the day when you could to preserve the life of the machine, and the reasons for upgrading were always for improved performance or functionality, but never because I did not have enough RAM.
As a final example if people had acted on the advice to buy a machine with 32GB of ram a year ago, before the M1 was released to future proof their machine, they probably wasted their money as I suspect in 5 years time they will not be able to upgrade their hardware to the latest version of Mac OS, as in my opinion it is unlikely to support Intel Hardware.
In general the best advice is to spend money on what you need today, and don’t worry too much about the future, because when the future comes it may invalidate the choice you made.
