Elon's next millionaires start October 24? (Ad)

SpaceX minted 4,400 millionaires in a single day, and Tesla has turned more than 5,000 employees into millionaires. One welder's $10,000 stock package made him a millionaire on IPO day. Former Wall Street CEO Dylan Jovine says Elon Musk's next venture could outsize everything he's built before. It runs on an obscure AI firm Musk has relied on since 2012, supplying crucial technology to Tesla, Starlink and SpaceX.tc pixel

Elon says the ‘S’ word (Ad)

Elon Musk and Sam Altman have sued each other and feuded for years. Yet within days of one another, both men described the same moment in strikingly similar terms: a technological tipping point they call the Singularity. James Altucher says the idea once belonged to science fiction. Now he connects it to a move Musk could make as soon as October 21, and lays out what both men see coming in a short presentation.tc pixel
