About that content: back in the days there were numerous podcasts about Ruby or Rails or both. That was when podcasts were hardly as omnipresent as they are today. There were newsletters, blogs, and every e-learning platform had many prime tutorials on rails.

Those aren't all gone. But in the grand scheme of things, Ruby, and Rails' have been relatively decimated. There now are about twice as much (web) devs as back when it started but Rails nor Ruby is hardly twice as big. It's been going strong, solid, flatline.

I wrote a longer post, a while ago, with sources and numbers on this. It was featured on HN https://berk.es/2022/03/08/the-waning-of-ruby-and-rails/ (and frankly, it's going faster and is worse than I predicted back then)

(disclaimer I am the curator of first and the maintainer of the second)

From where I am, things don't look the same as you are describing them:

1. https://newsletter.shortruby.com - it is younger than 1 year, but you can find a lot of new content there: new podcasts were released in the last 12 months, new conferences were organized, and new books were announced. When I say new = it means never done before, not new editions.

2. https://rubyandrails.info - while it is not a comprehensive directory, it has a lot of resources. Indeed the youtube courses section is empty, but that is due to my lack of time, not because they are missing

3. Also, take a look at this https://rubyconferences.org

I don't have time to debate everything you wrote in the article, nor do I think I can change your mind.

I also don't know the future. Maybe you are right, maybe you are wrong. I choose to believe that Ruby is not dying and act like it: launch a newsletter, start to write a book, and prepare some more projects.
