Why would I share technological innovations with another company? Because nobody has a real market until some of these problems are solved significantly better

Why would I share technological innovations with another company? Because nobody has a real market until some of these problems are solved significantly better than current state-of-the-art? Having some baseline collaboration on common components and safety systems could plausibly move the entire industry towards viability much faster, both on a safety and tech trajectory and for regulatory oversight. It's not a crazy idea.
