Modernization can mean replacing 50 year old technology with "20 year old" technology. I stuck in the quotes because something that is perceived to be that old is probably under active development, and modern while remaining boring.

There are different 50 year old technologies. Fortran is older than that, but still going strong in some niches because for a few niches it works good enough. (for some numeric operations it compiles to the fastest code and that matters). COBOL is older than that too, but everyone is replacing it because nobody wants to know it - even those who do know it prefer something else (or so I'm told - I don't work here). C is more than 50 years old, but it works good enough for a lot of people and it is still getting better. C++ is nearly 50, and getting a lot of useful features. Rust is todays hotness, but it continue or just be another fad - ask me in 30 years.

I've seen many fads over my lifetime and I expect to see many more. Some fads I regret their death, while others I'm glad we saw the light and don't use that anymore.
