🤯 Similarly there was a discussion on HN that this is essentially reverse engineering and zero API/ABI guarantees, cam break wity any update, and the response "once the language becomes popular enough, Microsoft will have to honor and keep it anyway"

Gaming stocks are dropping today after Google's rollout of Project Genie, an AI tool that lets users create and explore virtual worlds for 60 seconds. This is the result of a market that does not understand how video games are made. Allow me to suggest that the Street read Blood, Sweat, and Pixels

This might annoy some of my colleagues (game developers and low-level tinkerers that get furious about Electron et al. memory, latency, and CPU usage): I agree and started to realize it even before vibe coding.
It's not just "fashion" to wrap everything in web frameworks. 1/N
It's not just "fashion" to wrap everything in web frameworks. 1/N
after 2.5 years of vibe coding, my biggest takeaway? native apps are dead. iterating for the web is so much faster, has better tooling, and lower overhead. low-latency, multi-projector, 3d, spatial audio, custom hardware—ai will continue to have trouble with these.
