Imagine if Earth is entirely water. The poor fish can develop mega brains but they would still be more or less stuck under water with no real viable technologie

I mean, aren't dolphins, whales and orcas already have pretty much close to human-level intelligence?

  No? They are very smart, but human level? Not even close. They are similar to apes in intelligence perhaps. That's not human level.

    I mean, I think that one of the reasons humans are smart is just because of writing so that the knowledge gets passed down with much more ease. I think if these animals could write and read somehow they would be just as smart (if not smarter) than some humans :)

      People who can't read or write aren't less smart than other humans. No, there are no animals at all, anywhere even close to the smartness of humans. It's not a small difference, it's a HUGE gap. When we talk about how smart apes, or dolphins are, we are talking relative to other animals. Relative to humans, it's almost nothing.

As land creatures, we haven't explored the underwater tech tree in much detail. If there are fishpeople with mega brains out there somewhere, they might have figured out some stuff that we haven't.

  But not fire, probably, which is a key to many tech trees (e.g. smelting, cooking).

    Many of those processes can actually be done biologically by enzymes, without needing high temperatures.

  like fire, metallurgy? They are stuck behind bronze age. I just don't see any technology without having these things as prerequisites. Even electricity is generally impossible when you live in a big conductor.

  There are certain limitations we know about though. Like that making a spaceship would be more difficult. Not only getting out of the water and then into space, but just that you have to have your capsule at a higher pressure. Though landing might be a bit easier because you don't have to use boats to get people out. But then landing and exploring another planet will be much harder, and don't get me started on what their airlocks would be like. Or clean rooms! Hell, anything optical or electronic you're going to have a much harder time with.

    On the other hand, biological systems tend to use copious amounts of water to facilitate not just chemical reaction, but also keeping things moving (at molecular scale) or suspended and protected from shocks (at macroscale). It's easier to float things in water than in the air. The water-people could thus have certain advantages in their technological process. (On the other other hand, salt water is metal killer...)

      > (On the other other hand, salt water is metal killer...) I think this is the key. The modern world is an electrified world. But the other things you point out are in some cases advantages are also disadvantages. But I think the biggest thing is metal and electricity.
