The construction kits have commercialized the redundant parts of most popular genres, so the nature of commercial production has changed - it's like this in almost every industry. Not much scratch food in a restaurant anymore...
I think it means, however, that for producers striving for uniqueness, it's even more important now to work outside the establish genres, which is not easy - you risk alienating your listeners. And how many people can invent/reinvent a genre?
Else, you may have created every sound on your deep house track from scratch, but no one will know.
(I'm one of those OCD people who almost never even use presets, not because I think it's lazy, but because I'm working for my own enjoyment, and enjoy scratch baking. But if I were a commercial producer, I'd be broke. Who's gonna pay me for a day of making my own kick drum, 'cause the masses will say "I never heard a 60 hz sine wave decay quite like that"?
