Apple's bet on India to escape China risks just hit Trump's tariff wall. Stock down 17% as AI strategy fails while competitors soar. The company that once led tech innovation now trades at premium prices for mature-company growth.
OpenAI launches its first European AI data center in Norway with 100,000 NVIDIA chips by 2026. The $1 billion facility joins a global arms race as tech giants plan $300+ billion in AI infrastructure spending this year alone.
Arm Holdings abandons its licensing model to build chips directly, potentially competing with customers like Nvidia and Amazon. The risky pivot sent shares down 8% as the company bets its profitable business on a crowded market.

Gradient descent is an algorithm that helps AI models learn by gradually adjusting their parameters to reduce errors.
Think of rolling a ball down a hill to find the lowest point. Gradient descent does the same thing with math - it finds the combination of settings that gives the model the fewest mistakes.
The algorithm takes small steps in the direction that reduces errors most quickly.
Gradient descent is how most AI systems learn. Without it, neural networks couldn't adjust their billions of parameters to get better at their tasks.
It's the engine behind nearly every AI training process.
