considering the lab experiment with just one laser required a sound level of about 140 decibels that consume 20 gigawatts, I don't think holodecks are going to be a practical device.
WHAT DID YOU SAY? I CAN'T HEAR YOU OVER MY HOLO-WAIFU
"NOTICE ME SENPAI!!1"
Great points, but you know how things go. Proof of concept is a bloated laboratory implementation, then the tech gets smaller and more efficient over time. Next thing you know the sound is outside of human hearing range and the laser projector is fitted to a drone.
More realisticly how things go, experimental research only works in lab conditions, clickbait article suggests it's coming next year, people make giant assumptions, people lose faith in science because the promised thing doesn't arrive
Lol probably, we are definitely more on track for cyberpunk or idiocracy than star trek post scarcity socialist utopia
According to the article it's already using ultrasound.
Ultrasound at 140 dB which can still seriously damage hearing, you just don’t hear it happen.
So they can only do holodeck simulations of EDM shows.
It may be interesting to see how humidity and temperature influence the laser (or even other gases as mentioned in the article)
So like, ten years at most
It was the laser that's 20 gigawatts, according to the article, which is notable because such a laser is hard to redirect.
As for the viability of holodecks... Obviously the rest of your points are still valid, but one can only hope that someday we'll figure something out, the technology being impossible/unviable right now doesn't mean it'll stay that way. And this seems to show a theoretical possibility of manipulating light mid-air in the necessary way.
