Quotes from known names in a boring corporate press release are absolutely standard. It gives journalists a hook to build a story. “Elon Musk says new Nvidia tech is…”
You're right they usually do this, I checked some press release from last year. The big difference is that it's now the CEO that had to write the blurb instead of (e.g.) a vice president of product.
Yeah I imagine that when the stakes are as high as they are with Nvidia they pull out the biggest names possible, partly to drive media but also as social proof. “All these important CEOs are prepared to go on the record - not just corporate droids who have to because it’s their job”.
