Yes, there are concerns about eventually radiation effects for the users, due to the wireless connection between iPhone and AirPods, what in fact is a child play compared to this. Hot to mention the possibility for unauthorized access to the users phones this way.

144 antennas means 144 amplifiers, and a 144-path phase modulator (unless it clusters them into sectors such that when in one quadrant of the device, the other three quadrants' antennas are inactive) or 144 coherent oscillators. The radiation precision would also depend on the tolerances of several components in each of the amplifiers. It's basically a track-while-scan RADAR.
Based on the last time I dealt with active phased array tech, that base station is likely over $750 in parts alone.
This unit may be fairly large, but if you look at where this technology started take a look at the SCANFAR (SPS-32+SPS-33) radar panels used on the USS Long Beach and USS Enterprise built in the late 1950s/early 1960s. Each panel was about the size of a small house. The newest equivalent, the SPY-1 radar array variants, are much smaller but still very large and consume a significant amount of the power budget on their host platform. But while sharing the technology these are also solving a different problem. Wireless power transfer (WPT) is much more narrowly focused and the beamforming is targeted at increasing the power transfer efficiency, which at 5 watts per device is still far less efficient than plugging in a USB or Lightning power charging cord.
Glad to see the world finally catching up to Nikola Tesla from 100 years ago. He recognized the relationship between radio and electrical waves and their connection to the wireless transmission of power. He even built a tower to do it -- but ran out of money when JP Morgan lost confidence in him and pulled his funding. Tesla, one of the world's greatest innovators died broke.
He may not have died broke if he enforced some of his patents. Marconi built the radio using Tesla’s ideas in part. Tesla didn’t care about making money anyway.
Imagine what he’d have been able to do with more modern technology.
I think it is not so much the case as apple waiting to see the technology improve but they seem to have to reverse engineer it to try and make their own Ie camera chips were Sony ( best in world ) then they decided to buy a cheaper option from China I’m actually a bit miffed and embarrassed by the fact that my iPhone has parts maybe made from forced labour from Chinese companies ( lenses) and now apple setting up production lines in India when the government is beating its own people and foxcon not looking after it’s workers in India and what I’d really like to see is NZ getting the speakers for our homes we can’t even buy them here but they are in Australia they have been out for years now . Even with all the staff at apple all of those incredibly talented engineers can’t even make the Apple TV use voice recognition in NZ . I love apple products I’ve used them for decades but it just wears me down a bit when other companies catch on to what they are up to and they can produce it faster on there own production lines apple was first but now we get old tech and huge prices wrapped up in old revamped designs.
My wife offered me her iPhone 12 Pro but I’m happy to stick with my iPhone max ( which can’t restore my Face ID app and I’ve restored it but it now has glitches.

It's the smallest 144-path active phased array I've ever seen. And it isn't really solving a different problem at all. Both are intended to deliver a lot of RF energy to a remote point with moderately high precision. A TWS RADAR looks for the reflected energy, while this is sending the energy to be harvested at the destination, but that distinction doesn't matter to the power transmission part.
The only functional difference I see is that this doesn't use information from the transmission to determine target location. It instead uses a side-channel. Compared to building a 144-path active phased array antenna in the first place, repurposing this for hobbyist RADAR would be trivial.

No, there aren't. There really, really aren't. People have worked around far higher levels of RF energy for nearly a century with zero long-term health effects. With long exposure to high levels of power (significantly more than 5W), you can get something vaguely like a sunburn. A bit higher than that focused on your eyes, and you can boil your vitreous humor. The heat is the only real risk, and that's mostly a risk because you can't see it to avoid it. I'm an Extra-class radio operator and have been dealing with kilowatt-range RF for over a decade.

It's not clear to me that the unit described is even a scanning radar. It sound like it is simply broadcasting a beacon signal and a transponder in the target device is used to determine its 3D coordinates. If you wanted to repurpose the array for general purpose radar scanning operation, sans the transponder dependency, it seems like you would have to implement all of the receive side signal processing including receive beamforming functions. This would not be something that I would personally consider a trivial hobbyist exercise. Plus, it's not clear to me how many concurrent transmit beams can be supported from a power budget standpoint, so you may have to sequence/scan the transmit beams as well. Again, this doesn't sound trivial - to me.
From a hobbyist standpoint I'd be waiting for something like Echodyne's metamaterial electronically scanned array (MESA) radars, which start at sizes not much larger than a smartphone with effective ranges in the hundreds of meters to drop into a price range that would be attractive to hobbyists. With the number of emerging applications that rely on radar, including autonomous vehicles and border security, become more pervasive I have no doubt that the costs of this technology will come down substantially.
Xiaomi's wireless power transfer (WPT) is a novelty and interesting first step in a direction that has a lot of potential. But it's going to seem like a wringer washing machine in no time flat. I suspect that future WPT technology will be integrated in a conformal way into building/home designs, much like current light switches and power outlets. It's not like you have to plug every appliance and electrical fixture in a room into a single power outlet (I hope!) so having multiple and less intrusive WPT arrays located in a single room should not be an issue, especially when coupled with other forms of proximity sensors to know when they are needed or can remain idle.
but will add that Elon Musk claims the wireless technology that Nikola Tesla had in mind has been glamorized by modern people. I faintly remember Musk saying it will take a lot of wireless power to charge a light bulb.

I have no idea if Musk said that -- but it sure sounds like something he would say.
If Musk didn't invent it or design it, according to Musk, its no damn good. That's not to trash Musk, I have a great deal of respect for the guy. But humility is not one of his strong points. And, to his credit, he speaks his mind without pulling punches -- its refreshing.
Been telling iKnockoff morons for years that “wireless charging” is just a marketing term.
True wireless charging doesn’t have *ahem* wires.
Would be crazy to see a knockoff Apple company create something original.
It wouldn't be crazy at all. It happens all the time!
As for wireless being wireless, at some point there's a wire but not between the power source and the device being charged. That, gasp, is totally wireless.

Lol. Good information for @Beats to reflect upon. But I don't think it is EVER going to happen. He will be stuck in 2007/2008 forever in his life. Whatever happens after that does NOT matter to him.

You don't really need a phased array on the receive to pick up reflections from normal objects. Take the current targeted sector from the transmission system and work out the distance to an omnidirectional (or very vaguely directional) receiver. Doing it that way, you don't have to chirp the transmission to deal with self-interference in the signal path; you can practically transmit CW. You only need steerable receive on military RADAR to try to defeat stealth.
My real interest is less in hobbyist RADAR per-se as it is in certain other applications of phased array antenna tech.
