What is the most peculiar thing about the human brain?

Our brains are slow

The mystery becomes even greater when you think about the limitations of our brains. Computer scientists use bits per second to measure the rate at which a computer can handle information. An ordinary USB bus on a laptop computer can handle 30 megabits per second. In contrast, Human beings can understand speech or read text at 45 bits per second or less.

For many other tasks, our brains can only handle around 10 bits per second. That huge brain we have only allows us to keep a handful of items in our working memory at any one time.

If our normal body temperature is 98.6 degrees Fahrenheit, why do we perceive weather in the 90s as "hot?"

Macaque monkeys, having just 7% as many neurons as we do, are smart enough to use stone tools.

You might claim that we need gigantic brains for language but songbirds with tiny brains have some of the basic elements of language. The brain of a Blackcap Chickadee, for example, weighs less than a gram and has just 157 million neurons.

My answer is based on an article written by people who are as mystified as I am:

Why do most atheists in debates with theists take Bible verses out of context much of the time? Are they lying maliciously or do they not understand theology enough to understand the meaning?

That huge brain we have doesn’t give us strong multitasking abilities. Try listening to someone talk while you are trying to solve math problems. I bet you can’t.

Lots of mammals get by with tiny brains. Mice having just 71 million neurons can do all the things they need to do to survive.

It’s hard to understand why we need such big brains to accomplish the things we do.

Why can't the US government force this new deep seek to not operate in the USA for security reasons? People's personal information will be available to China like TikTok was.

Our brains have 86 billion neurons. Insects manage complicated lives with microscopic brains. Fruit fly brains, for example, have fewer than 200,000 neurons. That’s enough for them to analyze information from their senses, find food and mates, avoid predators, walk, communicate, etc. Fruit flies can navigate in the air, avoiding the many obstacles in their environment and responding to air currents and rain. Human pilots require lots of training to do that.
