FYI, Nintendo Switch is Tegra based as well. 61 million units isn't bad, and there are significantly more Tegras in use in Switch consoles than in Jetson boards or even Telsas (~1 million).
But it hasn't really seen the broad based success in mobiles they were hoping for, yet.
(By comparison, a midsize mobile company like Oppo sold 115M units in 2019)
