Looks like Sony and Panasonic are still making them. Sony will be your most likely candidate to make them basically forever: https://www.cnet.com/tech/home-entertainment/lg-one-of-the-last-holdouts-ceases-production-of-blu-ray-players/

I just looked at my nearest brick and mortar store‘a website and they have a broad selection of LG, Sony, and Panasonic Blu-ray players in stock.

Because the bitrate over streaming is garbage. Get physical media if you want good 4k.

Decades, if not longer.

This sounds amazing.

Not at all, OnStar is a wholly owned subsidiary of GM.

Yes, specifically by the teams assigned to these products. Things like OnStar have been able to remotely unlock the vehicle to provide access to first responders for decades.

Most cars can be remotely unlocked. Anything with an emergency crash detection system or even just an emergency button (usually on the rear view mirror or ceiling console certainly can.

That’s just market forces, then. I suggest domestic workers adapt or retrain in a new industry.
