Su's right that the tech industry is competitive, especially with Nvidia being all up in people's faces. But I don't think she's worried about keeping up - she's more concerned about staying ahead of the curve. That's a smart move, considering how fast AI is evolving.
And yeah, there are some challenges to overcome... like export restrictions and getting chips into customers' hands. But Su seems to be taking it all in stride. She's not afraid to take risks and make big bets on this tech. Which is good, because if AMD doesn't jump into the AI game now, someone else probably will.
