No, because heat doesn’t absorb/spread instantly through food, through material. If you cook it twice as fast for half as long, you’ll get a too-hot outside and a too-cold inside.

Now… at 6,000 degrees, you’re past the auto ignition temperature of the food and parts of the oven itself. It’s going to burst into flames any moment now… I’m surprised it’s still a solid object. You don’t wanna make it that hot :-)

Give that podcast a listen if you are interested. Speculation wasn't the right word to use. Behavioral and cognitive evolution is very real, but also very fuzzy.

The strong relationship between language and music in the human brain has been long established in neuroscience through a number of experiments.

What I found to be uniquely interesting about this theory is that where we already knew that our ability to understand music is deeply related to our ability to understand language there is now a theory that explains how this relationship evolved and why that relationship has to be so.

The dopamine response to song provides a clear evolutionary benefit. For birds that benefit seems to be limited to mating. Humans are a eusocial or prosocial species. Both the ability to positively regulate the mood of other members of a society and the ability to have your mood positively regulated by others is an extremely beneficial adaptation. Extreme isn't a strong enough word. These abilities are likely hard requirements for intelligent prosocial species. Selection pressure for cooperative and affinitive behavior would have been immense. Humans have developed prosocial abilities in many ways. Ability to enjoy music is an example of one of those abilities

Understanding music would then be something that just comes with the ability to learn vocalizations, speech and language. As we evolved speech and language abilities, the ability to understand music just came with it. Enjoying music as opposed to just comprehending it is an exceptionally beneficial adaptation for a member of a prosocial species.

Eeeeehhhhh releasing dopamine is how 'liking things' works in general; I don't know if that really counts as explaining why our body's would come to reinforce that behavior.

For example, your brain releases dopamine on an full stomach, because it wants to reinforce that behavior, but that's not a 'why' as much as it is a 'how'. The 'why' there would be more related to the fact that from a survival POV, it's important that you eat as much as you can when you can.

We don't really have a compelling reason as to 'why' music creates a dopamine response, unless I missed something in your post.

There was a quick snippet at the end about a speculation that the same networks in your brain that can learn speech are necessarily receptive to music; which if so would be an interesting quirk in evolution that makes sense as to why it's seemingly connected to complex vocalizations. But from what I understand, that was labeled expressly as a speculation.

I think the fact that “The call of the void” scares us is the point. Like other people said, we have the thoughts to consider what would happen if we did certain things, when we realize how bad the outcome would be, it scares us. Humans are really good at classifying or naming things so we eventually started calling rational thoughts about suicidal actions, “The call of the void.” A scary name for a scary thought.

Brainwaves are not timed fetch/execute cycles like computers but that doesn't mean there's not anything to this comparison.

Computers are built from the ground up on timing. Perfect sequentialling is required for computers to function. One thing happening out of order will shut the entire system down (some exceptions). Neural networks (even when simulated in software) don't have that strict ordering requirement.

Timing of networks in the brain allows for more efficient messaging with other networks. This results in faster computation and lower energy consumption.
