Because of how wide and thin it is, it looks like a phased antenna array to me. It’s a way to create cheaper, performant antennas. You see this form factor with a bunch of RF applications in UHF to EHF range.
Here’s an example of a random mmWave radar board. Imagine a plastic case over this to keep out dust and rain.

The large flat one looks like radar to me. I hadn’t heard of radar being used with PTZ cameras. But you can also use it standalone to measure traffic flow.
If it isn’t radar, it’s something with a large, flat antenna (probably a phased array). The other two options I can think of are a long-range RFID scanner or a point-to-point network connection.

Is this a cool innovation? Yes. Over 100Gb/s wirelessly in a data center would be really cool.
Does this “rival fiber optic speed”? No.
Lay people don’t get how crazy amazing fiber optics is. Right now you can buy an off-the-shelf optical transceiver that does 800 Gb/s with a pair of passive fibers over 2km using a single wavelength. Why does it use a pair instead of a single fiber? Is 400 Gb/s the max you can transmit on a single fiber? No, it just makes the transceivers easier to make. I don’t know what the upper limit is per fiber, but it’s probably north of 100 Tb/s.
If this piques your interest, check out the Grace Hopper cable. It’s designed to carry 352 Tb/s across the Atlantic on 32 fibers. With all the protective layers, the cable is about the size of a garden hose.
I largely agree, but one situation I can think of where condensing the work makes sense is experienced professionals who already meet the learning outcomes. Their goal is to prove that they know the material, then have a degree to show as proof, not to actually learn the material.
