That’s unfortunate to hear. Jellyfin does definitely suffer the from the problem of not having a teams developing apps under a unified banner. You can make your own, provided you’re determined enough, but guidance from the core Jellyfin team is not to be expected.

Roku, yes. Xbox as well. PS5 no, but not for lack of trying. That’s apparently on Sony.

Not an expert, but molten salt reactors are correct. MSRs are especially useful as breeder reactors, since they can actually reinvigorate older, spent fuel using more common isotopes. Thorium in particular is useful here. Waste has also been largely reduced with the better efficiency of modern reactors.

Currently, Canada’s investing in a number of small modular reactors to improve power generation capacity without the need to establish entire new nuclear zones and helps take some of the stress off the aging CANDU reactors. These in particular take advantage of the spent fuel and thorium rather than the very expensive and hard to find Uranium more typically used. There’s been interest in these elsewhere too, but considering how little waste is produced by modern reactors, and the capacity for re-use, it feels pike a very good way to supplement additional wind and solar energy sources.
