I went to Walmart two days ago, and on the way out of the store, I saw a mopping machine that was automated to clean the floor. Although I was surprised to see it, I wasn’t surprised that Walmart automated a cleaner away. Although I was surprised to see it, I wasn’t surprised by the cleverness of the technology. Why? All of this was written on the horizon for a long time already. This reminds me of what Andrew Yang keeps on reminding us about as he is running as a presidential candidate — wall to wall of big brands’ fulfillment centers are being filled with robots. Anyhow, check out the short clip video that I took on my smartphone of a robot mopper.
