Of course it is relevant.
Look, up until literally the last gen, console hardware makers threw out everything they had from the prior gen and started from scratch with everything. That's just how it went. They did that because they needed to custom design these machines to maximize performance at the given cost, and devs went along with it.
So this idea that now devs and hardware manufacturers are totally married to x86 into perpetuity, forever, because that's what they use now, and even though the entire industry is starting to move in a different direction, they will stay on this platform, because they don't want to write another emulator that can run Skate 3 on ARM, is just bizarre.
If ARM continues its upward trajectory, if companies like AMD and MS continue to develop ARM CPUs, if MS continues to develop Windows ARM, if software companies continue to release ARM-native software, then the consoles will run on ARM, I guarantee it, and the market will shift. It's not that big a deal, it's happened many times in computing history, we used to have tons of architectures that all fell by the wayside.
You’re constructing revisionist history to suit your argument.
Console makers threw out all the code written for PPC legacy hardware last gen, because it was an uncomfortable necessity, in order to move to a more ubiquitous software ecosystem, i.e. x86, that already had a strong, commercial and extremely mature development ecosystem for high performance gaming on PC.
They knew they had to move towards a more PC-like architecture, because there was no way they could compete with the likes of AMD and NVidia designing their own bespoke hardware, and they wanted console developers to be able to leverage the wealth of software, tools and developer expertise that already existed in that ecosystem since the dawn of videogames.
In comparison, ARM offers them no such benefits. There is no such mature pre-existing software ecosystem for high perfomance games on ARM. High performance computing as it pertains to video games is still dominated by x86, and even more so now both console platforms are on board, and entire sub-markets for middleware providers supporting simultaneous cross-platform development have arisen off the back of the same.
You’re trying to argue that platform holders, games and app developers, middleware providers and every other major player contributing software tools and services to this industry would be willing to bear the unreasonable cost of re-writing, porting or emulating all their existing tools and technology for ARM, on the basis that it’s popular in a market they aren’t involved in and it’s just the latest hotness? It’s absurd.
The question you’re failing to answer is “why would they bother?” So far you’ve offered no a single meaningful reason all these private corporate entitites would want to take on all this additional cost in terms of time and money.
Enterprise doesn’t follow tech. Tech follows the needs of enterprise. That’s how it has and always will work in the real world of for-profit commercial markets and private corporations.
You’re also talking about “emulation” without any practical sense of what that would look like in terms of performance. Emulation for a low power, low performance, low clocked core like the Jaguar on PS4 might be doable, but even then, there’s no current ARM CPU design implemented in a commercial product, fast enough to be able to actually achieve this for performance-critical software like a video-game.
It’s one thing emulating x86 to run Windows, Word or a web browser, but running something like a videogame in emulation is well outside the realms of reality. Something like JIT recompilation is more probable (which is what most cases of x86 on ARM is doing), but even then, for something as performance-critical as a videogame, and for something like the x86 Zen cores on the current gen hardware it’s a complete pipedream. It’ll never be fast enough. And even if you could just barely manage it, why would you move to ARM for the benefit of slighty higher perf per watt, only to give that benefit up (and then some) by running all your software through an “emulation” layer?... makes zero sense.
