Getting tired of being sold what may exist or will exist sometime in the future. How is this legal and now Apple is doing it? How is the fake it before you make it (make the actual product a reality for consumers to consume) strategy legal? This video was posted a month ago even when Apple Intelligence wasnt available at all and in any form https://www.youtube.com/watch?v=TPe8revsg3k https://www.youtube.com/watch?v=TPe8revsg3k . Even present day after it was launched Siri can not do this. Start-ups and other tech companies are doing the whole fake it before you make it so Apple is too. Some recent examples...Open AI demoed and sold if you sign up you might get access to their version of H.E.R. yet Many months later its nowhere to be found yet surely that juiced their revenue. Does it really exist or it was a fake it before you make it demo? Similarly with Musk bringing out those robots implying they were AI driven yet later we learn they weren't. Isnt this all something called false advertising??
