Also, we really don't know how the Lucid software team is organized. It could very well be a group of backend engineers splitted in two (gravity / air) that handles all the low level communication with the car components, and a front end team working on the v3 redesign.
Most of what UX3 seems to offer on the software side, like multi task, was part of the factory day presentation last fall where they shared the roadmap of fdatures to be delivered by Q4 2024.
I wouldn't worry much as the glimps we got from some press reviews showcasing UX 3 shows off a lot of quality of life improments that shouldn't be too taxing for old 2022 infotainment hardware. Only time will tell, and I guess with Gravity deliveries starting in May, we'll get our Air UX3 soon enough
