It's almost like the lack of robust anti-trust prosecution by world governments have so enriched large, rent-seeking companies that they can literally afford to burn money and still come out ahead...

Phased arrays are very cool tech. Personally, I can't wait for visible-wavelength optical phased arrays to hit the mainstream (they're just now being implemented), since they'd enable tech like legitimately holographic displays and video cameras with digitally programmable optical zoom.

Have any further reading I can do on this?

This linked article says this chip was produced to support a standard that didn't catch on. It's not surprising that it's no longer in production if this is true.

I love how industry came up with ever crazier schemes to stream content from phones and laptops to TVs. There must have been three different attempts involving WiFi alone, but this phased array mmWave 60 GHz million bucks basic research abomination surely takes the cake. Meanwhile, some Google engineer realized you could solve 90% of phone-to-TV streaming applications and 100% of the hard technical problems by just t…

The founders obviously wanted to exit

Some companies are purchased only so they won't become major competitors.

Companies are not primarily purchased, but sold. The previous owner could've continued, but they've chosen not to. We can't dictate them what to do, right?

>yet the second the sale is closed 90% of the things that the company did that made it valuable are jettisoned

If it were valuable they wouldn't be jettisoned

Earlier quoted context omitted.

5ms isn't yet at nausea levels though...

In 2014, Michael Abrash gave a talk summarizing what's needed for a feeling of presence in VR. He said 20 ms motion-to-photon latency is required for the virtual world to feel like it's "nailed in place". So 5 ms is 25% of the latency budget.

The number I've heard, don't ask me from where, is 16 ms.

Lattice didn't exactly buy SiBeam. They bought the company owning SiBeam.
