Web applications don't follow Moore's law (Google developer)

Peter didn't read the same essay I did, he's fixated on some trivial statement, or he's deliberately setting up a straw man version of Joel's argument. Joel's point, as I took it, is that people too committed to rolling their own everything out of misplaced focus on performance _now_ are going to miss out on the performance and interoperability improvements that will be coming in the future.
Here's an example from Mac software history that Joel may be ignorant of: WriteNow, a word processor, was well known for being blazingly fast. It was the only application in its class written in hand-tuned 68K assembly. Everyone bowed before the WriteNow team's accomplishments...until the PowerPC Macs came along and made their codebase obsolete. Oops!
I'm not sure there's anything that people wanting to build non-trivial apps _now_ can do about Joel's vision of the future, except understand that it very well may be coming.
