I do think the Apple flowchart and LinkedIn person may be working on a future project and not the iPhone 13. Also, I'm skeptical enough that I question the screenshot and flowchart, wondering if they are genuine. It wouldn't take much to fake either to make them look like Apple was involved, or LM was involved.
Still, I agree there is a lot of room for optimism. This is the first time, may ever, that Liquidmetal has the hydra/maze of connections to make something awesome in mass quantities. If it doesn't pan out I'll be in shock. I give it an 85-95%% chance of all being very very real.
