Is There a Smart Grid for Electricity?

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: Why does Occam's razor work? - Stephen, do you know how to cook? - How would you explain the goal of your physics project to a 5 year old? - Yuval recently indicated that the next pandemic (crisis) will be an attack on the internet. What do you think? - What did you think about that strange shaped asteroid passing the solar system, which caused speculation it was an interstellar voyager? - Going back to the original thoughts of the "net" but based on new but now almost existing tech/Software? The important part of the attack on the Iranian Uranium system was that it was done through the electric grid and not the "internetgrid". Explaining how that is relevant and possible would be enlightening to many. That can be made a mainly physics answer. - In the Wikipedia article for Outmuamua they say "it did exhibit non‑gravitational acceleration" - what does that mean?
