Weirdly enough, Google, Amazon, Facebook, IBM, and Microsoft announced a partnership this week to conduct research and promoting best practices on AI.
Why is that weird? It's just a trade association. Its purpose is to come up with a minimal code of conduct in the field of AI so that the government doesn't impose something more stringent, to give what may be mistaken as an independent body to take complaints about its members to, and to the extent practical to establish ways to restrict outsiders from entering the market. This is perfectly normal, every industry with money sloshing around has them. It doesn't mean the companies don't compete (or indeed engage in anti-competitive practices against one another).
