Perhaps, but I doubt it. The immersiveness and suspension of disbelief come partially from the richness and massive bandwidth of the data stream players receive. Streaming degrades it massively. Even with media streaming, e.g. Netflix, there are many folks (including myself) who can't stand the low-ish bitrate they _have_ to supply to customers because of the infrastructure strain / $REASONS. With games it will be even worse. And there's also the latency problem, which is kinda massive for this. Unless of course they invent some kind of protocol where assets are stored and loaded on the console, but the logic of the game is received via a low-bandwidth stream.
Regarding your post: I think the future of RE of server-side bound software will be something like 1. Point your AI robot with eyes and ears to an interface designed for you (the human customer). 2. Make it explore software at massive speeds, map and record every possible behavior, closely construct/approximate the human-computer interaction model. 3. Rewrite it completely in Rust. 4. Profit.
There will be no moat. Popular non-FOSS will be laughed at and rewritten by its users in hours/days. Proletariat will finally own the means of production, and the Stallman dream will finally become real.
