Something i can't understand in chapter System Design -> Scalability

[CuberL]

Usually, web applications can be scaled by adding resources unless there is no state stored inside the application.

I can't understand this line at all. In my opinion, stateless systems can be scaled horizontally easier... Why the article says unless there is no state stored inside the application ? 🤔

thanks @CuberL for catching this. looks like a typo. Will get it fixed :)
