    Also:

    At this rate steam on linux will hit like 10% in a few years.

    The general desktop marketshare of linux is slightly higher than the steam. Its at like 4.5% already

    One other factor that also influences Linux' market share is that a lot of people just don't use PCs anymore and rely only on smartphones. I assume that Linux users are less likely to stop using PCs completely than Windows Users are (or rather, that people who don't even get into PCs would have been less likely to become Linux users if they did)

    So it's not just direct conversion from Windows to Linux, but also a higher retention of users somewhat.

    Sorry, Windows still dominates the computer OS market.
    Except for computers that are small, computers that are large, computers that are very fast, computers that are resource-limited, computers most used by normal people (mobile) and computers most used by enterprises (server VMs).

    But desktop computers that are used to launch MS Office or games, boy does Microsoft still dominate that market.

    Most corporate servers in general run Linux, let alone webservers. Intel literally used Minix without attribution in their Intel Management Engine, so technically every Intel chipset motherboard with an IME runs Linux. That's basically every Intel motherboard since 2008.

    I am reminded of that one time we went to lunch with one of our scrum masters and he actually said "why does linux even still exist anymore".

    I didn't even get into all of that i just told him i switched my home pc to linux a few months ago lol

    I know Lovense Lush uses a Nordic nRF51822 microcontroller, this doesn't run a full OS normally. It runs ARM machine code directly, usually programmed in a C variant in something like Keil. They provide an SDK with an Arduino compatible platform, so it might even just run Arduino. No idea if someone analysed the software on those microcontrollers as it's pretty niche and the code inside is probably super simple. The microcontroller is way overpowered for what it does, but it isn't that overpowered that it could run a full Linux stack.

    I remember watching a talk about sex toy hacking once, I'll try to find it for your (and everyone else's) pleasure. Think it was a Lovense in that talk

    Not even the more expensive microcontrollers run Linux.

    The kind of thing you would see in such a simple device like a dildo are the cheaper smaller ones with RAM sizes and Flash Memory sizes in the KB range and costs less that $1 in bulk.

    Mind you, you can squeeze a Linux kernel into a really small amount of memory, but why for a production device pay more for a larger than needed microcontroller and then use most of its storage for a Linux kernel leaving little space for the actual functional code when you don't need support for things like filesystems or networking?

    Microcontrollers are a whole different world from microprocessors.

    Linux on microcontrollers was a thing back in 1998.

    More modern and capable microcontrollers like the fairly cheap ESP32 can run linux pretty well.

    You can force it to happen (because the Linux kernel is quite modular and you can make it way smaller by switching off a lot of things) but as I said, what's the point when all you need is to literally run a single application that only toggles I/O ports or does a bit of comms with an external integrated circuit via I2C, Serial or SPI?

    In a production design for something as simple as a dildo - so basically a motor controller - there really is no point in paying for a more powerful and more expensive microcontroller, adding cost to the final product, just to stuff a Linux kernel there to run a single application that doesn't need things like filesystem or networking support.

    (For example, here is an example of about the most low end microcontroller you can use. Notice the 128 bytes of RAM and 2KB Flash storage. You can stuff enough code in there to activate a motor in one of several specific simple cycles depending on the position of a switch but not much more. Of course that kind of stuff is programmed in C either directly on top of the hardware - by literally changing microcontroller registers - or most likely on top of a manufacturer specific low level library)

    Further if you do need functionalities of an OS such as multiple task/application support, there are alternatives that tend to be better for those kinds of use, such as various RTOSes.

    Now, as many pointed out, there's plenty of reason to do it for the challenge or the fun of it - the ethos of any good hacker in the traditional sense of the word - just not for a production design of a device for which tens/hundreds of thousands of units will be made where adding Linux raises the needed capabilities of the microcontroller and hence the hardware cost while not actually helping to deliver the needed functionality.

    It's very slow, but some people made a RISC-V rv32ima emulator that runs on an ATMega328P to run Linux on an Arduino Uno. Nobody would do that in a commercial product (it's ridiculously slow, difficult, and further into "for shits & giggles" than Taco bell with laughing gas), but even the cheap shitty microcontrollers can run Linux. Badly.

    The microcontroller probably runs Zephyr, not Linux. It's fine, Zephyr is also sponsored by Linux Foundation.

    “Linux never succeeded” is such a funny take when it’s quietly running most servers, phones (Android), and a ton of embedded stuff. The real Linux rule is: if it works, nobody notices 😄

    Hopefully not, the only reason it would need linux is if it connected to wifi and I don't know who wants that.
    Anything up to bluetooth should work with just a Microcontroller running nothing more complex that a small rtos.

    For running a vibrator, you'd probably can do with an ESP32 or RPi2040. No need for the big guns (pun intended).
