If it has sentience

it’s being used to protect us? Now that is thoughtful:

Imagine a medical-advice chatbot that lists fewer diseases that match your symptoms, because it was trained on a narrower spectrum of medical knowledge generated by previous chatbots. Or an A.I. history tutor that ingests A.I.-generated propaganda and can no longer separate fact from fiction.

Just as a copy of a copy can drift away from the original, when generative A.I. is trained on its own content, its output can also drift away from reality, growing further apart from the original data that it was intended to imitate.

In a paper published last month in the journal Nature, a group of researchers in Britain and Canada showed how this process results in a narrower range of A.I. output over time — an early stage of what they called “model collapse.”

Apparently, visual artists have been attempting to poison the models for a while now, to the point where they can’t tell the difference between a cat and a cow. Turns out even in Plato’s Cave you need people who know things.

But using itself to replicate itself is, shall we say, projecting deformity.

Hapsburg AI, indeed.

Nothing for Water

One of my colleagues is being interviewed and quoted widely about this week’s deadly tornado in Oklahoma. As he tries to makes sense of the connections between extreme weather and climate change, I sure hope he can get through to some people who have been, let’s say, stubborn about the whole thing.

But another issue that is bad enough on its own but also brings that broader issues into focus is the draining of the Ogallala Aquifer in Texas. It’s important to remember about global warming and its associated devastations: the Earth will be fine – it’s people that won’t survive, especially difficult without water:

The Ogallala Aquifer suffered its second-worst drop since at least 2000 in a large swath of the Texas Panhandle, new measurements show.

The closely watched figures, published this week by the High Plains Underground Water Conservation District, cover a 16-county area stretching from south of Lubbock to Amarillo. The Ogallala wells measured by the district experienced an average drop of 1.87 feet from 2012 to 2013. That makes it one of the five or 10 worst drops in the district’s more than 60-year history, said Bill Mullican, a hydrogeologist with the district.

“There are some pretty remarkable declines,” Mullican said. One well in the western part of the water district, he said, dropped 19 feet over the year.

The vast majority of Texas is enduring a drought, but the Panhandle has been especially hard hit, causing farmers to pump more water to make up for the lack of rain. That depletes the amount of water stored in the aquifer over the long term, which means future generations will find less water to pump to grow crops.
