I don't understand the hostility, nor the downvotes to my original point. You're going sideways a bit trying to deliver your message to a captive and mostly agreable audience where I was attempting to answer OP's question asking for insider information about why all the servers and supercomputers run Linux and pivot into adoption and advocation for Linxu in general.
I agree that we need to embrace FOSS on mobile. I'd LOVE to have a viable Linux-distro phone that actuall works. I spend money and effort in this space, already. The vast majority of the world gets connecitivity via mobile devices. I know that and probably most in this community do too. My original point (heavily downvoted in a linux sub of all things) is that Linux IS READY and can WIN the desktop. That's it... that's all. Yet it seems you've taken umbrage that I didn't agree with you 100%. In fact, we could really just consider linux on mobile as a smaller desktop with more input constraints and a smaller screen + need to utilize mobile radios properly (this is typically the hard part to open source). And I agreed with most of your statement, correcting on one point that implied Linux was only suitable for Servers. Which is a bit ironic because to win mobile it HAS to win on the desktop. Steam and stable / high UX distros have made this actually viable in the last 2-3 years where Windows users can migrate with the lightest of disruption and capability yet get all the resiliency, security and privacy.
You're not winning anyone over with the attitude. I don't get the edgelord response like I personally affronted you for having a nuanced interpretation. Geninuinely asking - what makes you think attacking me with your italicized ad hominim is working, especially when it's the hottest of takes? Are you getting out your anger on someone? Makes you feel like you're "winning" a comment thread on a tiny internet forum? Who hurt you, man! :-) In all seriousness, in the real world, we'd likely be chattering on about this over a beer, so I truly don't get it.
Happy to continue the conversation, in the hope we can find common ground. Not everyone's an idiot because they don't agree with you 100% or see things from another angle. In fact, I'd like to discuss this:
Outside of offices, computing now means Android and almost nothing else
If you're going strictly by number of mobile devices I buy it. If you're going by actual dollars spent, arguably the most important metric for investors, I'm going to say the disparity is narrowed by gamers alone, even if mobile wins by sheer volume x cheap devices. Mobile currently drives investment by selling personal data and microtransaction games mostly, so there's anti-incentive to even ALLOW linux-based mobile devices on networks outside of Wi-Fi. So I see mobile as a near term hope and goal and desktop / gaming as an already winning, which just needs people to spread the good word. Plus people who run Linux on their laptops are much much more likely to consider it on their phone if it "just works" and covers 95% of their use cases and comes bundled with not selling or leaking their personal data for the same price.
