Note: I select clips with insights from these much longer conversation with the hope of helping make these ideas more accessible and discoverable. Ultimately, this podcast is a small side hobby for me with the goal of sharing and discussing ideas. For now, I post a few clips every Tue & Fri. I did a poll and 92% of people either liked or loved the posting of daily clips, 2% were indifferent, and 6% hated it, some suggesting that I post them on a separate YouTube channel. I hear the 6% and partially agree, so am torn about the whole thing. I tried creating a separate clips channel but the YouTube algorithm makes it very difficult for that channel to grow unless the main channel is already very popular. So for a little while, I'll keep posting clips on the main channel. I ask for your patience and to see these clips as supporting the dissemination of knowledge contained in nuanced discussion. If you enjoy it, consider subscribing, sharing, and commenting.

Michio Kaku is a theoretical physicist, futurist, and professor at the City College of New York. He is the author of many fascinating books on the nature of our reality and the future of our civilization.

Obviously Kaku has never overclocked his GPU

[gasolinewine]

“Why would a computer simulate Saturday Night Live” is the only thing you need to hear from this video.

[JonasDygd]

If the universe really is a simulation, then we cannot use the limitations of the universe we know as a definite measuring stick for what the fastest possible computer would be capable of. Our universe would be the product of the simulation and not really say much about the world in which the computer exists. For example, just because the speed of light is a limit here doesn't mean it's a limit in the world where the simulation takes place. On the contrary, if our universe is simulated, then it would be safe to assume that it's a little less capable than the universe in which the simulation is run... I'm surprised Professor Kaku hasn't considered this.

[lorddread]

Obviously, Michio Kaku has been assigned by the overlords of the simulation to keep the masquerade going. LOL! 🤣

[jimsomers]

He is assuming the universe running the simulation will need to have the same physics as this one. It's a baseless assumption

[willywonka]

Hes wrong because hes looking at the simulation from inside the simulation. Hes basically in the cave looking at the shadows.

[masonm]

Why would someone simulate something as huge as the universe? How do you know it's huge? What's the point of reference?

[guilhermeal]

He is wrong!!! As a matter of fact, the whole interior of the Sun is just a giant overclocked AMD CPU.

[ScorpionXII]

If we ever build a computer powerful enough to simulate the universe, people will be wondering if it could run Crysis.

[emrico]

To conserve computing power, a simulation would only render an object when it is observed

[Regan]

This is so ridiculous. We’re talking about the simulation coming from outside this universe and there’s no reason to limit the power of a computer that would exists outside this universe

[facepalmjesus]

a CGI human is NOT a ''simulated'' human. Is just an electric moving painting

people confuse the meaning between ''simulate'' and ''depict/illustrate''

[travislawrencemusic]

It's fun to read people's solipsistic and dogmatic scientism perspectives on topics like this. It's pretty easy to rule-out solipsism as well as to think outside of the scientific method to conceive of many more possibilities than Kaku seems to want to consider. In the end, the universe very likely exists in a manner that is totally outside of current ability to imagine. Maybe in our next evolutionary iteration, thru a transhumanist perspective, we'll b able to understand sooo much more than we currently do. Even in my own experiences, I sometimes feel like a chimp trying to comprehend the significance of Hamlet, i.e. I know there is something to experience beyond my current ability to perceive, because I catch glimpses of such a reality every now and then.

[rosewhite]

Only problem is he's assuming that whoever created us is using the same laws and has the same restrictions as we do.

[dudman]

If we lived in a simulated universe we would be as perfect as everything else, and we definitely are not. Instead we are both the most advanced and the most imperfect things we know of in the all of existence.

[joyboy-zx]

Games don't simulate the whole environment at once, they just render the part that you're looking at. So only the observed universe at a given moment needs to be calculated

[steves]

I love how the majority of you guys in the comment section support the chance we could be in a simulation, when I scrolled down I was not expecting it.

[danzigvssartre]

Every time computer scientists simulate the weather on their computers I put my raincoat on.

[steveheidelberg]

Michio Kaku is the man. This man is smart enough to know that this simulation talk is gibberish.
