Moore's Law should apply, and eventually processing power should catch up. I think we'll see the 2MB limit removed by 1997/1998.
That's a nice summary on the quality on web technologies.
2009: "Hey guys, we can now draw on a widget; we called it Canvas!"
2011: "Wow, look at this cool OpenGL wrapper that locks up your system in ways VoodooFX didn't manage to do in 1998! But you can use it on your web site, which is what people want, right, guys?"
It feels like we've redefined "progress" to mean "the same thing as 20 years ago, but worse"
More like the same thing as 20 years ago, but the dominant language is a LIS.. I mean a Schem... I mean it's a bit like Self.. look, it has garbage collection, a JIT, supports objects and goes somewhat fast. Oh, and it's used to drive a GUI made up of stringly-typed ... things that kind of looks like SGML and has no chance in hell of achieving good draw performance. But you can calculate fibonacci in CSS and get even worse performance than doing it at compile-time with C++ templates!
