That's ridiculous. It's as though EETimes is pretending there have been no Ryzen keynotes in the past.
Her keynotes have been way better than the average hardware keynote for some time now.
The thing that makes her better than many others is that she clearly knows and understands the technical details of her company's products, and she comes off as genuinely stoked about how great the products are.
Ever since the first keynote I saw of her for the early Ryzen announcements, I've been making a point to watch any keynote she's done.
