Steve Kornacki, NBC News' chief data analyst, stayed on air for as long as seven straight hours during this year's primaries as he took viewers down Election Night rabbit holes with his Kornacki Cam livestreams.

AI agents that pursue their own open-ended survival are an emerging security threat, according to a report first shared with Axios from the Center for a New American Security.

Its advisers include naval heavyweights, retired Adm. Lisa Franchetti, retired Vice Adm. Jeffrey Trussler and retired Rear Adm. Milton "Jamie" Sands III.
"European rearmament" is catchy,convenient, clean.
But the truth, across many capitals, and in the minds and hands of those building factories and weaponry, is far more complicated.
Why it matters: The continent is at a crossroads. Unpredictability gnaws at the relationship to the west with the U.S., and stray Russian missiles and drones arrive on its doorstep to the east.
While an influx of defense spending is a solid start, many bottlenecks remain, entrenched by regulatory, political, geographical and cultural differences.

One thing is already clear: Candidates increasingly can't afford to have half-baked AI agendas.
Elon Musk is looking to shake up America's wireless industry, potentially bringing the first major new competitive threat in years to a business dominated by three companies.
Why it matters: The cellular industry has seen enormous technological change but relatively little disruption to its competitive structure. Musk has the money, spectrum and satellite network to attempt something different — though he faces daunting obstacles.
