Just because something is old or uses old framework or old standard doesn't make it crap. Crappy code is crap, but it age doesn't make it crap. Code doesn't rust or detoriarate by itself.

Example if you write good code now using C++14. If it's good code now it will continue to be good code 20 years later. There's no property that adds bugs or "crappiness" to the code as the years go past. The invention of a new "c++40" standard doesn't obsolete old code or turn it "crap".
