    The bacteria being chased was totally beyond reason! How can something that small have the "intelligence" to chase anything!

    I’d definitely recommend checking out a book called “Vehicles” by Valentino Braitenberg. Or just look up “Braitenberg Vehicle” on KZread, there are a few really good explanations on there. Trust me, it’s relevant.

    The information were great but this video could easily be 10 minutes shorter if he spoke a little faster and smoother. Again I really appreciate that he filmed this because it was really helpful for me and I don't mean to be rude or mean.
