Hi Manize,
You raise good points in regards to the balance of capital and social justice. The fact is many profit-orientated businesses are very concerned about ethics and social justice in new technology and they are leading the discourses on the future of work and technology. Social causes, ethics, and sustainability are firmly embedded in current conceptions of corporate responsibility, as this is being demanded by consumers. I think Open AI fills an important role in this picture, as big businesses can invest in social justice-based AI research as part of meeting their corporate responsibility mandates. In other words, I doubt Open AI will have any troubles raising capital. Another important thing to keep in mind is that not-for-profit does not mean you have little money. It just means that you spend what you make.
