One problem with the current rash of AI's in the news is they are only backward looking. They only "know" that which was in the training data up until they were trained. So to incorporate new things you have to retrain them

This sounds like a great way to preserve privacy, use the same birth date every year for all people born that year. Then no one can use birth date as identifying information (it should never have been used that way to start with). The bir

Terahertz radiation has a new mechanism by which to cause harm, namely, it can alter and trigger chemical reactions between molecules. That is why the chemistry field is so interested in it, as per the article. So while it is not ionizing

That makes sense. The radio system could be a much lower power, low baud rate system though, enough to transmit commands and get a little telemetry but much smaller than would be required for constant communication with Earth. This may al

So far I haven't seen anyone mention the big deal here, that Starshield is offering to take over ANY satellites communications entirely using lasers. A customer no longer has to include a radio system on their satellite (unless that i

My take on this, although it is not entirely clear from the article, is that Epic wants to move most of their computing to the cloud and Google felt left out and now they have a hospital chain who wants to partner which gives Epic a reason

A lot of web pages already have a copyright notice, why doesn't that stop AI's from training on the contents of web pages? Can you train AI's on patents? Or on binary executables? Or from cameras that observe the public?

Good wishlist, but how do you measure risk in a trained ML algorithm? What does reliability and stability mean? How do you measure bias? How much accuracy in results is enough for a specific purpose? These are all still research questio
