Regarding the post - I'd say that the collection of vst's is the product of a hoarded mentality (humans love to collect things) combined with an unfounded hope that said collection will increase their production skills. In many ways it does serve as a pathway to expand the way one's mindset works whilst making music, little by little, but often it's done in a way that's counterproductive or useless.
From a post I made about software hoarding, and the necessity to focus instead on the development of artistic skills.
I'd just like to say that I agree with this. I acknowledge that the diversity of tools does have the profound ability to expand the artist's mindset. But I believe this expansion should only happen at the appropriate times in the artist's development. It should not happen in the beginning when the artist just approaches their tools for the first time. It is honestly hard enough just to figure out the basics in computer music, even with how easy everything has become.
It also is a great sign of curiosity that shines favorably on the artist's disposition. But that natural and beneficial curiosity needs to be restrained to strengthen the core, the foundation of the artist's coming personhood. <-- no that is not a euphemism for masturbation.
I really feel that when an artist is in all honesty satisfied with their work, they should definitely go out and try new things. It is a gateway issue, it is at the beginning of a plateau of struggle, not of artistic interest or capability. When things become too easy, expand and challenge the workflow that has taken so long to develope. Break it, and see what emerges, what new ways there are to do things and think about sound and rhythm and your vst directory.
But in the beginning, it is hard enough to climb one mountain, why climb fifteen all at once? How incremental, discouraging, and maybe ultimately fatal (for the stated purpose :) ) would such an endeavor prove?
Again, this is just from my experience. Ymmv.
