It's obvious that up to this point, proprietary software has created a vibrant ecosystem and immense profits that probably would not have existed were all software open source. It's driven the computer revolution, which is the most significant shift in technology and user behavior in living memory. I would argue that open source technology has been a much more "vibrant ecosystem", and that open source software is creating a much more "significant shift in technology" than proprietary software is. I don't think it's reasonable to say anything about what the world would be like "if all software were open source", or how that would happen.
