The Future of the Industrial Market Is in Berkshire

This question comes from Stewart Boyd who's a chemical engineer from Australia he says currently Berkshire would be incredibly difficult for an activist investor to target. Warren and Charlie after your ownership has been completely distributed will Berkshire be more vulnerable to activist investors I'm guessing this isn't something that keeps you up at night but thought it was worth asking. No it's gonna happen quite a few decades after my death. Yeah I don't think I'll believe bothered much better.
