tr:dr; he says “x86 took over the server market” because it was the same architecture developers in companies had on their machines thus it made it very easy to develop applications on their machines to then ship to the servers.

Now this, among others he made, are very good points on how and why it is hard for ARM to get mainstream on the datacenter, however I also feel like he kind lost touch with reality on this one…

He’s comparing two very different situations, more specifically eras. Developers aren’t so tied anymore like they used to be to the underlaying hardware. The software development market evolved from C to very high language languages such as Javascript/Typescript and the majority of stuff developed is done or will be done in those languages thus the CPU architecture becomes irrelevant.

Obviously very big companies such as Google, Microsoft and Amazon are more than happy to pay the little “tax” to ensure Javascript runs fine on ARM than to pay the big bucks they pay for x86…

What are your thoughts?

    Once they’re very competitive in performance they’ll simply start replacing Intel with ARM and nobody will complain because at that point the 90% of developers are using Java/dotnet/Javascript (things that run on VMs) will not even notice the difference between running on their amd64 or ARM.

    They need to get competitive in performance first, and they haven’t been for a few decades now.

    Even still, developers will know, because their Docker images suddenly stop working. I’d agree with you for shared hosting setups, in the manner PHP hosts and a select few Python hosts will allow you to upload files onto a shared server and run them.

    Even in devops environments, I’m pretty sure nobody is actually juggling raw source files around the servers. Everything is getting neatly pipelined, and those pipelines need to be changed or the code will simply break.

    I don’t know what PHP is doing in their datacenters, but Facebook is not exactly a nornal software company. Their open server architecture is pretty neat but I don’t think they influence any companies but their own in their push for ARM.

    All of that said, I agree that architecture shouldn’t be a problem in practice. If you’re a programmer and you don’t know the difference between ARM and amd64, you’re going to run into much bigger problems than “something is up with my build”. In practice, though, I expect Linus to be right, and that ARM will remain a niche product for at least the foreseeable future unless Ampere manages to pull off the stuff they’ve been promising for years.

    There’s one exception, though: small, new IoT startups are moving to a very Raspberry Pi-based ecosystem, to the point of devices literally including full Raspberry Pis. Intel seems to be losing the “small computer but not microcontroller” market pretty badly.
