Not necessarily. It can just mean using one that came out this decade instead of last. It's clearly silly to re-architect every year, but it's not absurd to do an update/reconsideration once every 4-5 years, especially at a smaller company.

On the other side, there's plenty of new tech that my company isn't using yet, but will let me study or send me to conferences to learn about. Just because you work somewhere that's still built on old tech doesn't mean you can become proficient with newer ones. Especially if you're planning to look for a new job at a company who likely does.
