Why would my species expose their brains through a glass dome?

There doesn't need to be any advantage. Your species simply thinks it is aesthetically pleasing. Look at human history. We do all sorts of strange things in the pursuit of beauty. Depending on the ...

Why would my species expose their brains through a glass dome?

It is precisely those diseases and bacteria that make the brain need to be visible and, potentially, accessible. The bacteria and diseases attack the brain from the outside in, and they leave ...

How much mayhem could I cause as a sentient fish?

Make someone overreact So you swim to North Korea (hopefully the tank was not too far). Once there, you regroup in the shape of a submarine and you slowly approach any US/Japanese/Chinese/North Korean/...

How do telecom companies survive when everyone suddenly knows telepathy?

you can't pick a single or group of known targets to do private messaging or group chats! This ability is pretty useless for communication. It's like entering a cafeteria during lunch time, what you ...

Can a rational creature have a series of small brains instead of a large one?

Yes. For large animals, octopuses are a possible source of inspiration. They have neurons in their arms, which lets them have a very large brain-to-body ratio. This does let their arms move without as ...

How much mayhem could I cause as a sentient fish?

Let's shut down and/or melt-down some nuclear power plants. Heck if some brainless Swedish jellyfish could do it in 2013, surely a gang of criminal salmon can manage!

The Physiology of people living on a world with 9 year days

Firstly, if your only reason for the hemisphere-sleep adaptation is the inhabitants' constant migration, you might want to reconsider. A 9-earth-year day means it takes more than 78000 hours for a ...

What kind of world would drive brains to evolve high-throughput sensory?

This answer may be voted as non-responsive, but I think your question may be missing your point. You assert that "filtering out" the unimportant stimulus is a sign of slow or incomplete processing. ...

Justifying why mind uploading destroys the brain

Solution #1: your scanners don't have the penetration they need to read through brain matter (or skulls). There is no scanner with the kind of penetrative power you need to scan things at an atomic ...

What would be a way to make uploading a mind into a computer an actual transfer instead of just making a copy?

Hans Moravec had some interesting ideas on this sort of thing in the late 70s and early 80s, which are detailed in various books including Mind Children. There's no freely available online copy of ...

On average? Not at all. It's a simple application of the pigeonhole principle: $x$ bits can convey $2^x$ different messages. $x-1$ bits can only convey half as many messages. You cannot fit all the ...
