It will reach 10% in 2050 thereabouts, given current velocity, assuming current computing models are still relevant by then.

Well, in the overall kernel space there is nothing but Linux-based kernels right now.

		You should broaden your hardware horizons. Straight out of Linux Foundation, https://www.zephyrproject.org/ There are no Linux kernels on Sony PlayStation nor Nintendo's Switch, or even Microsoft's XBox. Windows with its 80% market share has no Linux kernel. Zero Linux kernel running on the ca 15% Apple desktops. Zero Linux kernels running on iOS and iPadOS. No Linux kernels on Arduino or ESP32, althought they certainly can run ESP-IDF and FreeRTOS. And then there are INTEGRITY, vxWorks, QNX, NutXX, FreeBSD, OpenBDS, DragonFly, IBM i, z/OS, ClearPath MCP, OS 2200, ThreadX, SphereOS, Fuchsia,.... and plenty more I won't bother to list, none of them with Linux kernel.
