> do you also say that about hdd space?

For slightly different reasons. My game drive is using about 900 GB out of 953 GB usable space - because while I have a fast connection, it's nicer to just have stuff available.

Same for some projects where we need to interface with cloud APIs to fetch data - even though the services are available and we could pull some of the data on demand, sometimes it's nicer to just have a 10 TB drive and to pull larger datasets (like satellite imagery) locally, just so that if you need to do something with it in a few weeks, you won't have to wait for an hour.

It’s counterintuitive but I learned this best by playing RTS games. If you don’t spend money your opponent can outdo you on the map by simply spending their money. But the principle extends, everything you have doing nothing (buildings units etc) is losing. The most efficient process is to have all your resources working for you at all times.

Why he wouldn't say it about HDD space? You buy HDD to keep them empty?

And as for the money analogy, what's the idea there, that memory grows interest? Or that it's better to put your money in the bank and leave it there, as opposed to buy assets or stocks, and of course, pay for food, rent, and stuff you enjoy?

It's the same in all three cases: using HDD space, money and RAM for good purposes (disk cache) is useful, wasting it (Electron) is bad.

(Weird side question: are you by any chance the Jason Farnon who wrote IBFT?)

> about money in the bank?

Yes, generally. That's the entire idea behind the stock market.
