Free cross-platform is a good thing, I agree, though it comes at the cost of lowered interoperability and inconsistency with other applications and OS's conventions - which is a big usability issue. But the "build quickly using simpler web technologies" part? That's a problem right here - it essentially makes it easier to create low-quality cookie-cutter app, instead of forcing people to do this well. It's not that much more effort to learn something beyond JS, but it seems that these days a lot of devs think their education ends at their first job.
Could have been gchat if google had any clue how people work outside google. Instead they’re trying to write my emails for me.
