Dark screens help but until we can project on something that’s essentially black they won’t be great for daytime viewing.
Unless/until some material comes along that is tuned somehow to only reflect light that comes from the projector, they'll have to remain limited to dark rooms.
You don't get to make black over a white surface in daylight.
And yes, it is not going to be as good as a TV outside in broad daylight. But they are almost definitely good enough to use inside with the curtains open. And if the light isn’t directly in your eyes like a monitor, do you even have to code in dark mode anymore?

Hopefully never. People who don't wear glasses don't need something on their face to watch TV, people who do need glasses don't need to worry about AR googles meaning they have to choose between seeing a screen clearly or everything else and nobody has to worry about the AR goggle company watching and logging everything you see and plastering everything in your line of sight with ads.
I don't think physical screens are going anywhere anytime soon. I wouldn't mind having every wall in my home capable of being a screen though. Screen-as-wallpaper would be very nice since you could create smaller virtual screens on any wall wherever you needed one and it would mean you could change your wallpaper/color on a whim.
When 100" micro-LED panels come out, the projector is going away for good.
Basically, any system that requires your eyes to focus on a physical screen that isn't the same distance as virtual objects will piss off your brain, because it knows something is going on, and hates being tricked without consent. Some people I think can ignore this effect to some extent, others cannot. It also strains your eyes more than focusing on an actual 2D screen so increases eye fatigue compared.
