Most 4k tvs, or at least the 250 dollar TCL model I have, support 4k at 60hz over the newer hdmi spec. It works fairly well as a large monitor, even when sitting up close.
Personally I don't think I'll ever get a <=60Hz monitor after using one with 144Hz. (Caveat- there aren't many 4K 144Hz models the last time I checked, and they're quite expensive. I'd rather make due at 1440p, any day!)
It'll probably be more like auto insurance companies where they offer a voluntary tracking program and if you're better than average you get a discount
We're already headed in that direction, for sure. The company I currently work for doesn't run a program through the insurance company directly, but they do make the company contribution to your HSA dependent on you participating in their wellness program. Bonus points if you have a smartwatch that can feed data back. Supposedly none of that info gets back to the company or insurance, but I wouldn't bet on it.
The health insurers have been relatively "smart" (more accurately, subtle) about this by this separation of the tracking/privacy implications into separate "Wellness" programs. In many cases these Wellness programs do seem to be firewalled from insurers with the only information passing between Wellness and Insurance being the simple abstracted metrics of "Level" or "Points", and that by way of presumably only the Benefits coordination aspects of corporate HR.
Though there are still questions of how strong the firewall is in cases where the Wellness programs and Insurance providers share parent companies or even just C-Suite members. Arguably, the separation allows corporate plan buyers to pick and choose Insurance and Wellness program separately, allowing for some competition between them on things like privacy. Yet, being employer-driven "benefits" first and foremost, it's hard to say how much the end consumer/user/employer's privacy is always prioritized, as it is an indirect need of the market.
(Also, every employer I've seen the Wellness program didn't define HSA contributions but rather "discounts" on Insurance premiums, which does seem to indicate that Insurance companies are probably using the Wellness program for risk pools, even with what little data they supposedly are being fed across the firewalls.)
