I wouldn't. Blazing fast, fearless concurrency, etc. are all super cringe at this point. Just say it's fast, secure and reliable or something like that.

I tend to agree. It makes me think that a project is more interested in optics / following trends and is likely overstating things.

Instead of "Blazing Fast", just show a chart showing you are better per core than XYZ.

Instead of "fearless concurrency", show that you are better at utilizing system resources than XYZ.

No it's not.
