True, the web was not originally intended to serve applications. But phones weren’t originally intended to either. For that matter, computers weren’t intended to replace TV, and cyclotrons weren’t originally intended to reheat frozen burritos. Yet here we are. It’s just basic innovation. And maybe if Berners Lee had the computing power we have, he would have envisioned a wider range of applications than serving static content.
Of course there’s value in questioning the status quo, and finding better tools to serve a purpose, but pooh-poohing the application of old technology to new purposes (especially when the technology has been updated to better serve those new purposes) just comes off sounding like a stodgy troglodyte.
