I know use cases are different but I can't imagine 95% of people needing more than 16GB of RAM especially with mac os "unified memory". I have intellij, pycharm, firefox, slack and a mongodb instance running on my windows laptop and its only using 10GB. Who knows how much of that 10GB could be reduced.
