In a not so-distant future dystopia you can only get monitors without ad-overlays, when you pay for the monthly subscription ...

You'll get the first month for free, when you sign up for the 2-year plan for 19.99$/month right now!!

Oh no, you'll pay the subscription AND you'll get ads. That's what Amazon Prime feels like atm, preroll ads for other shows at the start of everything you play (even next episodes).

I've wondered about this. The TV I have (a Sony Bravia) is now almost a decade old (works fine). We got it specifically because it has a slot for a DVB-T module (terrestrial broadcast). DVB-T is now gone (replaced by DVB-T2, but I doubt this will remain in the air long), so we have no broadcast TV now, only our HTPC connected to it with Netflix, local media files, and a browser.

Frankly, we don't miss the TV channels. Streaming works okayish for the public channels, but we rarely bother.

The TV is just a dumb screen connected to a receiver, which has the HTPC as input as well as record player.

So the only thing a 'TV' offers me is its screen. Is that any different from a high end computer monitor these days? Is there a difference based on the viewing distance perhaps?

Another difference between a typical TV screen and a typical monitor is many TVs will dynamically adjust brightness depending on what's displayed, and maybe other factors. Sometimes this is on by default and you can turn it off in a menu, but I've met TVs where you can't turn it off.

Using a TV which adjusts the brightness depending on what's displayed can be very unpleasant when trying to do computer work on it. E.g. opening or closing a window may cause other windows to abruptly change brightness. Scrolling through a document may cause the brightness to vary.

Historically monitors has better pictures at the expense that you couldn't look at them off angle, while TVs you could look at from anywhere in the room. I think that is gone today but it might be something that comes up again... Though in the safety critical application I brought up off-angle viewing is a requirement.

The problem with some monitors is that it gets tricky to get audio from hdmi that gets delivered to the screen

Sort of makes sense because a lot of people don't care about or plain don't want speakers on their monitor.
