I've never actually heard of most of that. I've never heard of semantic HTML and I don't know what a dialog element is.

I think a part of the problem is there are a lot of people doing web development that never actually learned it. I'm a backend developer who occasionally has to do web development and I never learned web dev. All my training was with databases and serverside code and all my coworkers are the same.

As someone who has worked with RoR in the last year, they've come a LONG way in the last three years.

Take a look at Turbo/Hotwire and other new implementations in RoR. They eliminate like 90% of the necessary Javascript and the libraries are reliable which is nice. A guarantee not always found in the npm ecosystem.

Plus they did create a lot of web development ideas/concepts that were later integrated into the "modern" approach of web development.

I will say though that article is sparse and not informative of modern Rails.
