The computer chip world is going through a massive shake-up.

For a long time, Apple was the "big boss" because of iPhones, but now Nvidia is taking over the top spot because everyone wants their chips for Artificial Intelligence (AI).

Investors are so excited about this change that when Nvidia bought a smaller company called Groq, their own value shot up by more than the cost of the deal almost instantly.

Experts think the whole chip industry will make over $1 trillion next year, but there is one big problem: memory.

There isn't enough high-speed memory to keep up with these powerful chips, and big tech companies are getting so desperate that they are firing bosses who can't find enough and sending new teams to live in South Korea just to beg the factories there for more supplies.
