I blame commercialization. These days everything costs half a billion dollars to produce and has to be run by marketing (and marketing's marketing) (and ad nauseam) and retooled to be exactly like the last thing that made a ****-ton of money, and by the time all's said and done you're left with a lifeless little shrink-wrapped nugget of bland.
There's still good stuff being created, but it is (almost without exception) weird little independent projects, not mass-market products.
