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?

Money analogy could better be put as one of:

1. Store your money in a 0% interest account—leave RAM totally unused—or put it in an account that actually generates some interest—fill the RAM with something, anything that might be useful.

2. Store your money buried in your backyard or put it in a bank account? If you want to actually use your money, it's already loaded into the bank.

Imperfect analogies because money is fungible. In either case though, money getting spent day-to-day (e.g. the memory being used by running programs) is separate.

Then why do you have any hard drive space available at this moment?

Isn't it obvious?

Because wanting to utilize something as much as you can to get your money's worth, and wanting to fully exhaust it as a resource are two different things.

HDD is for storage. RAM is for speed?

Why do you even need RAM when you could run everything from your HDD with much cheaper cost/MB.
