According to San Francisco workers, the hustle culture of the pre-pandemic days has returned in the form of long working days and weekends at the office. So called “996 work”, which originates from China’s tech scene, is a work schedule that starts at 9 a.m. and ends at 9 p.m., six days a week. The hustle isn’t new to Silicon Valley, but the hyper-competitive AI tech race and the fact that some employers are making 996 mandatory for its staff, or using it as a recruitment filter, could lead to uncharted territory. We talk about the origins of 996, the grind culture of Silicon Valley, and whether or not this trend is going to stick.

The scope of presidential power is front and center as the Supreme Court begins a new term. Cases on the docket will test Trump’s agenda, including his ability to levy tariffs and his attempts to fire Federal Reserve members. Also at stake are the survival of the Voting Rights Act, as well as a state’s authority to ban conversion therapy, and the rights of transgender athletes. We talk about how the conservative-leaning Roberts court might rule, and what role the Court will play in supporting or stopping Trump’s efforts to shape the country.

Amidst funding cuts, massive layoffs, editorial differences and Donald Trump’s ongoing attacks on media, more and more journalists and creators are leaving traditional media platforms and going independent. They’re turning to newsletters, Substack channels, Youtube and more, to keep doing the work they’ve been doing – but without institutional guardrails. As stalwart publications like The Washington Post are seeing a major exodus of reporters and as Paramount Skylark purchases The Free Press and hires its co-founder Bari Weiss as the new editor-in-chief of CBS news, we check in with independent journalists about the shifting landscape of the media.
