The single biggest threat to Republicans' long-term viability is demographics.

The big picture: The numbers simply do not lie. America, as a whole, and swing states, in particular, are growing more diverse, more quickly. There is no way Republicans can change birth rates or curb this trend — and there's not a single demographic megatrend that favors Republicans.

For 5 years, Elon Musk has been warning about apocalyptic runaway AI, calling it more dangerous than nukes. To stave off his feared future, in 2016 he launched Neuralink, a company to create cyborgs with the express mission of getting ahead of superhuman intelligence.

What's happening: Now, Musk says he has charted the long path to merging man and machine. In an elaborate presentation Tuesday night, he said his company has installed brain–computer links in rats and monkeys and aims to put them inside human skulls next year.
