>Maybe Ruby is not at the level where is was in 2007-2009 but it is also NOT in a downward trend.

It's not only that ruby and ruby on rails are trending down, this has been the case for at least 10 years.

This is only an article, but you will find the same point of view in many other places. The decline of ruby and RoR is obvious for anyone doing web development. Python is only getting stronger, Typescript the same, not to mention the statically typed competitors like Java with Spring Boot.

I wouldn't doubt that even languages like Go and Rust might surpass ruby soon in web development because as general purpose languages they are already more relevant.

I'm a former RoR developer and I took off the keywords ruby and ruby on rails from my curriculum because for me professionally it makes no sense to invest time in them.
