I hear you, Luis. I've been programming in PHP for more than 15 years and people have been dumping on that language and predicting its demise the whole time. But it's still here and at my work we have no plans to switch away from it.
Uncle Bob's got a nice essay on his observations the correlation between programming language evolution and processor speeds: blog.cleancoder.com/uncle-bob/2017...
I believe people are going to be maintaining C, C++ Cobol, Java, etc., etc., for the foreseeable future. If you are a good programmer and know a language with a huge number of lines in production, you'll probably always be able to find work.
So carry on and don't worry about learning the newest language (unless you want to learn it, of course).
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
