16 is overkill for you. 32 would be a waste of money. There is nothing coming in the next 8 years that will require 32GB of RAM. Heck, the MacBook Pro is overkill for you. You might want it, but you definitely don't need it.
Nobody even needs the internet. We lived and survived for centuries before the Internet. You might want it, but you certainly do not need it.
All we truly need is food, water, shelter.
