For like 95% of web applications, they probably could be ported to nearly any other web application tech stack with the tools we have now. We've been using HTTP GET|POST|PUT|DELETE for almost 30 years with HTML, CSS and JS on the frontend (with interludes of Flash, Java, etc. in clients). I think this AI hype cycle is going to lead to the tech industry spinning their wheels for a few years rewriting a bunch of things "just because I can" much like the industry spawned countless Javascript frameworks for a while (surprised we haven't seen more yet).
Instead of discussions about "my language/framework is better than your language/framework, see my TrustMeBro benchmark" - why not figure out what's next? Could we be working on the next set of patterns that are a level higher than OO design patterns like MVC, AR, etc.?
