Here's a breakdown of the context and implications:

Context:
Elon Musk was one of the co-founders of OpenAI in 2015, but he left the board in 2018. His departure was partly due to disagreements over the direction and governance of the organization.

OpenAI has since shifted from being a non-profit to having a for-profit arm, which has raised questions about its mission to ensure AI benefits humanity broadly, versus the pursuit of commercial interests.

Key Points of Musk's Statement:

Trust in Leadership: Musk's distrust in Sam Altman and by extension, OpenAI's current leadership, suggests concerns over transparency, ethical considerations, and the strategic direction of AI development. Trust in the leadership of any organization, especially one dealing with transformative technology like AI, is crucial for public confidence and ethical stewardship.

Control of Powerful AI: 

Musk's worry about who controls "the most powerful AI" underscores the potential risks if AI technology becomes too centralized or if it's managed by entities whose motives might not align with public interest or safety. 

Broader Implications:

Regulation and Oversight: This statement might be seen as a call for more regulatory oversight or different governance models for AI development to ensure it's not monopolized or misused.
Competition and Diversity: Musk's own ventures, like xAI, aim to provide alternatives, suggesting a competitive landscape could be beneficial for innovation and safety.

Philosophical and Ethical Considerations:
Musk has often warned about the dangers of AI, including the potential for AI to become an existential risk if not managed properly. His comments here can be seen as part of a broader advocacy for careful, ethical AI development.
Public Perception and Debate: Such statements from a high-profile figure like Musk can shape public discourse, influence policy, and affect the tech community's approach to AI development.

In summary, Musk's critique of OpenAI and Sam Altman highlights significant issues about trust, governance, and the ethical deployment of AI technology. These concerns are pivotal as AI continues to evolve and integrate into various aspects of society, necessitating a balanced approach between innovation, safety, and ethical considerations.
