With TVs starting to get USB-C inputs, which are displayport under the hood, hopefully HDMI fucks off.
Ballparking but it will likely take closer to a decade than not for that to actually happen... and I am still not optimistic. And there are actually plenty of reasons to NOT want any kind of bi-directional data transfer between your device and the TV that gets updated to push more and more ads to you every single week.
The reason HDMI is so successful is that the plug itself has not (meaningfully?) changed in closer to 20 years than not. You want to dig out that PS3 and play some Armored Core 4 on the brand new 8k TV you just bought? You can. With no need for extra converters (and that TV will gladly upscale and motion smooth everything...).
Which has added benefits because "enthusiasts" tend to have an AV receiver in between.
The only way USB C becomes a primary for televisions (since display port and usb c are arguably already the joint primary for computer monitors) is if EVERY other device migrates. Otherwise? Your new TV doesn't work with the PS5 that Jimmy is still using to watch NFL every week.
I've got bad news for you about HDMI then…
USB-C adapters for absolutely everything are thankfully quite common now thanks to the laptop/dock industry.
In the sense that we have dongles/docks, sure. In the sense of monitors with native USB-c input? These are still fairly rare as the accepted pattern is that your dock has an HDMI/DP port and you connect via that (which actually is a very good pattern for laptops).
As for TVs? I am not seeing ANYTHING with usb c in for display. In large part because the vast majority of devices are going to rely on HDMI. As I said above.
I'll also add that many (most?) of those docks don't solve this problem. The good ones are configured such that they can pass the handshake information through. I... genuinely don't know if you can do HDCP over USBC->HDMI as I have never had reason to test it. Regardless, it would require both devices at the end of that chain to be able to resolve the handshakes to enable the right HDMI protocol which gets us back to the exact same problem we started with.
And the less good docks can't even pass those along. Hence why there is a semi-ongoing search for a good Switch dock among users and so forth.
Regarding the Nintendo Switch, it's because of their engineered malicious USB-C protocol design that makes the console "Not behave like a good USB citizen should". It's less of an issue with the peripherals as a whole.
USB-C probably cannot replace either, because the unmating force is too light. A typical HDMI or DisplayPort cable is much thicker, longer and hence heavier than a typical USB-C cable (even those specced to carry high bandwidth, like a thunderbolt cable) because they need better shielding to carry high bandwidth signals long distances - it's not unusual to need to route HDMI several metres (but USB-C cables that long are unusual because of the different purposes)
For TVs and such it's useful to have the inputs connect vertically, so that they don't stick out the back of the device and cause problems pushing it against a wall. Then the weight of the end of the cable is going to be trying to pull the connector out of the TV. DisplayPort connectors can have a latch to deal with this.
Of course, there a ways around this: a new connector, for example. But it does mean that you can't just leverage the existing pool of USB-C connectors and cables to make this ubiquitous.
To mention, this is also a problem with HDMI (but not DP).
But just have the usb-c insert top down instead of bottom up, include room for a small loop and cable retention to ensure slack doesnt put pressure on the port. This easily allows for fixed connections with usb-c.
There are also side-screw locking connectors for usb-c. With HDMI, a top-screw option was made for more fixed install scenarios. That design is ugly af and uses a massive amount more room than the usb-c screw lock approach.
Could it be done with a tiny magnet?
Anything important enough to be secured you probably dont want to involve a magnet for.
Oh, screw lock as in like some PC tower cables? Yes, that would be really nice, I wouldn't mind that for a phone.
Exactly that.
Its mostly common on commercial devices still, but it is defined.

As an example:
https://www.startech.com/en-us/cables/usb31ccslkv1m
Though again, a lot of this could be mitigated with a loop, strain relief, and inserting from above into a port rather than letting gravity pull it down. But it would be nice to see side screw locks be more common with usb-c.
That usb-c connector with side screw locks looks like a future I want to live in.
It's futuristic, but it's open and not corporate. It's miniaturized and sleek, yet still mechanically rugged.
Just duck tape the usb cable to the back of the TV
A good USB c cable and port can hold quite a bit of weight, I've easily picked my phone up by it as long as you don't make any jerking movements. That's a lot more weight than a few feet of even a very heavily shielded cable.
Solvable by moving the locking mechanism out of the port and making one that you can retrofit to any cable
The connectors on the back of the TV can be oriented horizontally (like parallel to the screen, not perpendicular), which at least changes the pull force to a torque force, which isn't ideal but easier to hold on to.
