my estimate for startup in philosophy domain area: 10-50 blns$. output per year.about 2-7$ per person in world. And it is not about profit only, it can be about negative impact, about abusing of social environment for profit in short term with great lost in mid term. ISIS as an example with investment flow about 1bln per year with ancient technology ( not ancient, but 500 years old). if you have society ( it public company ) with 100k employees, then estimate per person can be based on proportion 1:1k with year salary as base. and 10mlns$ for integrated solution and maintenance does not sound expensive. Philosophy impact is less then climate change, infosec, biotechnology, energy( chemistry, physics, agriculture [not oil]), but has scale close to modern social startups, media and dream industry startups. Bigger then marketing, design innovations. Thanks to Павел Кириченко for impulse to compare with innovation in linguistics/philology domain area.
