the nostalgia for 1999 isnt really about missing dial up or basic html, its about mourning the loss of user agency. back then the browser actually worked for you. today the client is basically a hostile enviroment running megabytes of third party js just to track telemetry.
going back to gopher or text-only browsers feels like admitting defeat tbh. we can still build incredibly fast modern apps if we just stop treating the users hardware like an infinite resource for adtech. you dont need massive frameworks and client--side bloat to make something good.
