    I've always found the pigtail selector to be the coolest part of the process which just uses geometry to "select" a crystal that grows in the correct orientation for the turbine blade.

    Lots of trade secrets there. I wonder how many of them the BigAI companies have already collected.

      Considering most of those trade secrets are sitting in peoples heads or in documentation behind walls AI companies have yet to get over, not many.

        I think the issue would be mainly that people fail to realize the nature of what they're corresponding with, and take things from inside their heads and behind the walls, and put them into the chat?

        I hope you're right though.

      Can you name a specific example of a trade secret revealed in the article?

        I thought they meant it as "lots of trade secrets in the jet engine field" not "lots of trade secrets in the article".
