To me it's mostly about learning to mange RAM and storage space on your machine. A lot of stuff does not need to be hoarded on the machine. Move infrequently accessed data to an external drive. Be ruthless about purging stuff you no longer really need. Refuse to run apps that consume tens of GBs of RAM on a whim (looking at you Firefox, I've been impressed with how efficient and stable the Helium browser has been for me). If you are a developer, engineer for efficient use of RAM and storage.
Like I said, 16gb RAM and 512GB storage minimum is nice, but if the fundamental issues that contribute to massive and wasteful use of resources on our machines are not addressed, nothing will be enough.
