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.

A.I., A.I., captain!

Joseph Stiglitz, he of former World Bankiness, haver of the 2001 Nobel Prize in economics who warned that globalization was taking place at the behest international conglomerates rather than “forces,” now comes to light his hair on fire present similar cautions about Artificial Intelligence:

“Artificial intelligence and robotisation have the potential to increase the productivity of the economy and, in principle, that could make everybody better off,” he says. “But only if they are well managed.”
…
Beyond the impact of AI on work, Stiglitz sees more insidious forces at play. Armed with AI, tech firms can extract meaning from the data we hand over when we search, buy and message our friends. It is used ostensibly to deliver a more personalised service. That is one perspective. Another is that our data is used against us.

“These new tech giants are raising very deep issues about privacy and the ability to exploit ordinary people that were never present in earlier eras of monopoly power,” says Stiglitz. “Beforehand, you could raise the price. Now you can target particular individuals by exploiting their information.”

It is the potential for datasets to be combined that most worries Stiglitz. For example, retailers can now track customers via their smartphones as they move around stores and can gather data on what catches their eye and which displays they walk straight past.

The data farming of which we are all willing seeds know no boundaries, recognizes no politics and sees only profits. Shaded with the camouflage of complexity, it is a winning hand. Are we up for the ‘boring overwhelming’ of taking on the Tech giants? Wait, let me come in again…

Climate Debate: Over

In a quadruple over-time thriller that went so far past the wire it might be too late to do anything, climate change deniers are now providing evidence that climate change is actually happening and the scientific community was actually, uh, right:

In the press release announcing the results, Muller said, “Our biggest surprise was that the new results agreed so closely with the warming values published previously by other teams in the US and the UK.” In other words, climate scientists know what they’re doing after all.

The BEST report is purely an estimate of planetary warming, and it makes no estimate of how much this warming is due to human activity. So in one sense, its impact is limited since the smarter skeptics have already abandoned the idea that warming is a hoax and now focus their fire solely on the contention that it’s man-made. (And the even smarter ones have given up on that, too, and now merely argue that it’s economically pointless to try to stop it.) Still, the fact that climate scientists turned out to be careful and thorough in their basic estimates of temperature rise surely enhances their credibility in general. Climategate was always a ridiculous sideshow, and this is just one more nail in its coffin. Climate scientists got the basic data right, and they’ve almost certainly gotten the human causes right too.

Graphs and other keys to the idiocy at the link.

Well-funded liars = still liars.
