Much of Amsterdam and Florence is built on logs. Basically, just drive a bunch of poles in the ground until they "fill up" the swamp enough to create a stable platform. The anoxic nature of the boggy water greatly slows the decomposition of the logs.

There's definitely a metaphor, here. You don't have to completely fill the swamp, just fill it enough, with enough stable pieces to create a platform you can build on.

The value of AI output only decreases day to day as people do what there is to do with it. Soon if it can make something it will be making it for the 10th time instead of the 1st.

So yeah, we will hit rock bottom for sure. Eventually the value of anything that is genuinely new will rocket back up because we've spent so many years imitating imitations.
