You're tuned in to Tech Beat, and here's what's moving in technology today.
Starting with a quiet but consequential shift in how we measure time itself — global timekeepers have voted to retire the leap second beginning in two thousand twenty seven. These occasional one-second corrections have kept atomic clocks aligned with Earth's rotation for decades, but distributed computer systems have long struggled with the irregularity, and the looming possibility of a negative leap second — actually subtracting time — pushed regulators to finally pull the plug.
Turning to artificial intelligence and mathematics, Grant Sanderson of three blue one brown has published a thoughtful reflection on what AI tools actually mean for people learning and doing math. His take cuts against both the panic and the hype — he sees the moment less as a threat to mathematical thinking and more as a prompt to ask what deep understanding is really for, and why it still matters.
And on the hardware side, Engadget is raising a pointed question about memory chip shortages and what they mean for consumers. The argument is straightforward — if companies like Apple could once offer battery replacements for twenty-nine dollars, supply pressures on components shouldn't become a reason to abandon affordable repair options. It's a reminder that scarcity is sometimes a policy choice as much as a market reality.
