Well this is a tremendous step in the wrong direction. The economic problem is the ad supported model in the first place, no matter how it’s run. This is the same thing Google does, they keep user data to themselves and sell the ad placement. So now Mozilla has the same economic incentives as Google. Unfathomably bad move.

After doing some Meta/Facebook VR development in my job the lack of popularity made increasingly more sense. In brief, they’re both incredibly incompetent and transparently greedy.
I’m honestly baffled how they could spend so many tens of billions of dollars and have such bad software, it is completely bug ridden. You’ll hit a bug, research it, and find out it’s a major know bug for literal years they haven’t fixed. They care so little that they couldn’t bother to update the Oculus branding to Meta for over 3 years in various software tools and libraries.
Their greed might be more salient aspect preventing adoption, though. They transparently wanted to be the gatekeepers to everything “metaverse” related, a business model that is now explicitly illegal in the EU after years of being merely very sketchy. They are straight up hostile to anyone else trying to implement enterprise or business features. Concrete example: fleet management software, aka MDM. There are third party tools that are cheaper and much more featured than Meta’s solution, but in the last year they’ve pushed hard to kick those third parties out of the ecosystem.
I could go on, but in short nobody in their right mind would build a major business on their ecosystem. They’d rather let Meta burn billions in R&D and come back later. Besides, not even Meta is able to make money in the area now.

The original UE5 seemed slightly premature, the 5.1 and 5.2 updates were significant and non trivial to update to. It also seems like a tool that gives you enough rope to hang yourself. Unlike Unity, everyone gets ready access to the full engine source code. Fortnite runs UE5, so the performance isn’t inherently bad.

The headline is pretty misleading. The full quote states this being the studios debut game made several factors major problems. UE5 as the engine, a highly competitive genre, and a new IP made nearly insurmountable obstacles. For comparison, Doom Eternal, their obvious AAA competitor, was from a veteran studio with a legendary IP built on literal decades of custom engine experience. On the other hand, a game like Ultrakill can compete by having an incredibly tight scope.

Architecture emulation for current gen games is exceptionally unlikely right now. At a fundamental level, wine/proton doesn’t change the instructions the code describes, rather it translates the input and output. It’s a reimplementation of the same instructions in Windows. For architecture crossing you’d either have to create virtual hardware, which adds tremendous overhead, or recompile the binary. Recompilation is theoretically possible, but for x86_64 to ARM64, for games no less, it’s beyond the realm of mortals. It’s like how some jokes can’t be translated between languages; the structure and vocabulary is just too different.
If you’re honestly asking, LLMs are much better at coding than any other skill right now. On one hand there’s a ton of high quality open source training data that appropriated, on the other code is structured language so is very well suited for what models “are”. Plus, code is mechanically verifiable. If you have a bunch of tests, or have the model write tests, it can check its work as it goes.
Practically, the new high end models, GPT 5.4 or Claude Opus 4.6, can write better code faster than most people can type. It’s not like 2 years ago when the code mostly wouldn’t build, rather they can write hundreds or thousands of lines of code that works first try. I’m no blind supporter of AI, and it’s very emotionally complicated watching it after years honing the craft, but for most tasks it’s simple reality that you can do more with AI than without it. Whether it’s higher quality, higher volume, or integrating knowledge you don’t have.
Professionally I don’t feel like I have a choice, if I want to stay employed in the field at least.
