C or Death? Lets replace C with Rust.
SQL or Death? Lets replace SQL with NoSQL and now back to SQL and to something else?
HTML or Death? Lets replace everything with JS client side rendering.
PDF? JPEG? AAC? H.264 / AVC? x86 / ARM [1]? Every single thing that is 10 - 20 years old are considered old fashioned and we need to rip them apart without learning about their merits and pitfalls they went through. And sometimes as Alan Kay said only to reinventing the flat tire.
How about Better C? Better SQL? Better JPEG? etc And most if not all the time it isn't the language or spec that is the problem. It is the implementation. I am willing to bet we wont even have an Open Source SQL implementation that is as good as today's Oracle or MS_SQL in 10 years time. There are still insane amount of work on implementation alone.
It seems the Tech industry as a whole is in an eternal philosophy battle of throwing away everything and build something new vs improving what we have today and iterating on it.
[1] A prominent Intel engineers once said by the time you learn everything about Hardware design pitfalls from GPU to CPU and different ISA and be ready to design something truly so much better you will be at the age of retirement. I think this sort of hold true in other areas as well.
