the article seems more nostalgic than practical; languages/technologies that provide higher layers of abstraction generally prove to be winners in the medium to long run. i don't know if flex is the next big higher layer of abstraction for the web (and the analogy is a little broken because flex isn't really built directly on top of html/css/js.)

but i would love something that abstracts away the arcane bullshit that you have to deal with when manually dealing with html, css, js, browser incompatibilities, etc. in the same way that python/other HLLs abstract away the details handled manually with lower level languages (e.g. memory management, creating data structures more complex than a linked list, etc.)
