Here is a (more) accessible summary of my new work with A. Feder Cooper and others expanding memorization research from verbatim extraction of content from AI models to include extraction of works that are similar but not identical afedercooper.info/near-verbatim/
afedercooper.info
How much more extraction risk do we find when we count near-verbatim cases?
Measuring near-verbatim probabilistic extraction reveals significantly more extraction risk than its verbatim counterpart.

@polcz.bsky.social had a great conversation with the Majority Report about Bernie Sanders' "sovereign wealth fund" legislation that take equity share of these companies without any buy in and promises no bail outs.

One thing almost no one is talking about is how much the "AI bubble" is encouraged by the "promise" of wild profits [as long as several times more people are willing to PAY than currently use 'AI' for free or substantially subsidized]. A "nationalization" that empowers voters, not governments helps.

This call for democratic control of the AI frontier is so important! But why does @ezrakleinbot.bsky.social completely ignore the already introduced @sanders.senate.gov legislation that gives control of systemically important AI firms to the public? S.4825 does this!!

I haven’t weighed in yet on the new mountain of AI safety concerns, but to me it further elevates the case for an AI tax paid with stock. Depending on the tax rate, the public could, quite literally, be put in control. And not via the Pentagon, but a nonpartisan board created by Congress.

@polcz.bsky.social has a video interview with majority report on the sovereign wealth fund. Difference is that regular tax on corporations historically is easy to pass on to consumer but taking (not buying) equity shares ensure if any money is made the government gets a slice, and no bailouts

The public is entitled to a share of these companies, but not like this. This is just corruption. A bribe. A backroom quid prop quo deal. Taxes aren’t voluntary. And they aren’t case by case. Time to tax large AI firms with a payment made in stock.
