Maintaining such typing speeds look like a recipe for burnout to me. I think I could even see the CEO's hands trembling in the TikTok when he lifted them from the device after demonstrating 500 WPM. It certainly incurs a massive cognitive load, perhaps similar to what professional classical musicians can pull off—and they don't have invent the score at the same time as they are performing.

Someone capable of decent touch typing on QWERTY will hardly benefit from the additional typing speed IMHO; at least not when factoring in the time spent learning, and the inevitable decrease of typing speed on QWERTY keyboards which will be very hard to avoid when working in a team or multiple locations.
