    I know this sounds silly, but TB3 is the first port with both ends of the cable with male connectors.
    If one would accidentally connect 2 ports with one cable, would that damage the unit or nothing would happen?

    Using the supplied Apple charging cable that is correctly wired, nothing bad. I think the Mac tries to charge itself.

    TB1 and TB2 also had cables that could potentially be looped back in to the same MacBook.

    I don't, however, know what would happen. Hopefully nothing but I guess there's the potential for damage.
