So many people missed the point of this post that I ended up replying to it instead of them.

"Memory upgrade" means not relying entirely on your own memory and previous knowledge. That doesn't exclude internalizing the language, nor coming up with new solutions. It probably changes a lot depending on what you do, but I've found it imperative to keep up to date with an ever-changing engine, and it would have been malpractice to just rely on memory, and a great waste of my employer's time.

Not entirely related but I think its a good practice.

Anytime I learn something new, I create a simple project using that new thing as a way to memorize it better but also be able after few years revisit it and either remind myself about it or improve it.
