I work with typescript on a very large codebase. If I have the code editor open and the run a typecheck at the same time, plus some electron apps and Spotify playing, it can easily fill my 32GB of ram, so 64 would be the next cool number to not have to worry about ram ever.
Fuck Electron. I hate that current trend. I like my long battery life and being able to run more than 3 applications on my MacBook Pro.
I will always use the example of how I subscribed to Spotify for a couple months back in 2015 and realized that the app constantly sat at the top of the Using Significant Energy list on my mac and was the reason the fan was so loud. I switched away to Apple Music for that sole reason. iTunes by comparison was very power efficient. It plays music for gods sake. How can you fail at playing music that badly.
