Currently, there seems to be no tech that allows economical deep-sea mining. It is challenging, yet I can't see a compelling tech demo or explanation of why it nailed tech breakthroughs. There is not yet a shale oil moment. Looking at The Metals' top staff is also not encouraging: https://metals.co/company/ https://metals.co/company/ Most executives are not related to underlying tech. Most are not related to their hardest problem. Even the CTO has experience just with pure software plays. I found just one person who previously did some novel underwater robots as a principal. It is not professional due diligence, but it does not sound like a solid plan. I'm not sure why there is so much discussion about the environment, given that tech is not ready. Maybe after raising a lot of money, it's easier to blame regulations than admit challenges with execution?
