Linus is just talking sh*t like usual.

@markiel55 that's not an ISA vulnerability, that's an implementation issue. When Qualcomm SoC got another vulnerability discovered during the month, no one is fool enough to say that's an issue with the ARM ISA as a whole. And ARM by its structure has very few different architectures compared to Risc-V. As I said on another discussion, Linus shares his opinions/feelings on many IT topics he's far from an expert, worse sometimes he's even at the level of just any random user but uses his notoriety to rant. Here he simply wants to trow shades on disruptive companies he doesn't work with, that's all.

@NoidoDev This doesn't mean the guy is an expert on every IT related topics. Here he is just criticizing entire teams of hardware specialists based on absolutely nothing tangible while mixing concepts. That's far from the first time the guy shares unwise opinions with tons of assurance so he should be taken with a grain of salt every time he doesn't speak directly about his job.

@MikkoRantalainen Even if your interpretation is right, the critics are still valid: 1/ he's vague and it's still not related to the ISA itself, rather than being microarchitecture dependent. 2/ Spectre is 6 years old and was a shock in the entire CPU industry so pretty confident hw and sw engineers already thought about that when creating recent out-of-order/ prefetch mechanisms. 3/ Side channel attacks are generally not as easy to exploit as Intel specific issues like Meltdown or lazyFPU. 3/ It's really presumptuous to think engineers from many companies, sometimes very large ones, will not learn from the past and sometimes quite recent events. 4/ This guy is far from being as knowledgeable as Theo De Raadt on kernel security and he has some monetary interests in ARM and x86 development, making him suspiciously partisan.

@estranhokonsta being an expert on cooking doesn't make you an expert on farming. That's the same issue when years ago he shared his opinion about DE on Linux. Linus has the bad tendency to speak on IT topics out of his domain of expertise and people still preach his words like he is an expert. Saying arm is on par with x86 shows how much he is just a guy using cloud services, disconnected from the mess of physical implementations.

@estranhokonsta do you realize this is the guy whom the kernel is his sole job for decades and prefer using WSL to work? His opinion should have no weight on totally different domains of the whole OS or in IT in general. He should have the wisdom to not talk about subjects he doesn't understand.

@estranhokonsta it has to do with the fact he doesn't experience the OS as a user. This is an example of why you should take his opinions with a grain of salt. This "Arm is on par with x86" claim negates the user expérience of hundreds of thousands end users, developers and maintainers… and this has nothing to do with the ISA but the implementation inside a larger package.
