This author needs to go back to a time where you had to manage 512MB of memory.
People back then would've killed for 8GB now.
The problem I see though is software developers having a field day with not caring about optimizing and not making their software bloated as possible so that it doesn't require so much memory.
What kind of stupid world is it where 8GB of RAM is actually not enough? I'm not doing anything that fundamentally different to what I was doing 10 years ago, and back then 2GB was fine on the low end of things.
