I’ve used 4k and 1440p monitors, and my TV is 4k as well. For desktop use, 4k isn’t really a big difference because of the hardware needed to run it at a decent speed. However, once I got my hands on a 170hz 1440p monitor, I can’t go back to anything less. It’s extreme noticeable. The higher refresh rate, and the reasonable upgrade in pixel density makes text much clearer, especially in motion.

For content viewing though, 4k on a TV it depends on how much of your field of view is occupied by the TV. Most of time though, a high quality panel is worth much more than higher pixel density. There is a massive difference between a basic 4k big box store TV, and 4k LG oled. The color, even outside of HDR content is just so much better, and the true actual black color is fantastic. Resolution is nice, but honestly, oled color is so good.

If the price of labor was what determined the price, then why have prices gone up, when labor prices have not?

You missed the point of my example entirely. How can those commits exist, and those people exist in that instance if they don’t have accounts? I was refuting your statement that a frontend needs an account. By mirroring an existing repo, as an example, you could verify that my claim is correct. Git as platform is already decentralized and doesn’t require accounts. You could email someone your git diff’s and it will function the same.

You need a frontend

Yes, but the requirement of said frontend are very small.

and a frontend needs an account.

Not required at all actually. For example, mirror a github repo in gitea. You’ll see all the commits, their messages, and who made them. Yet that gitea instance isn’t accessible publicly. None of those people have an account, and none of them can login even if they could access the instance. A commit is just attached to a name, that is user configurable, and a lot less data minable than a “real” account.

People were uploading, and still are. Uploading a video for my friends, or a school project which needs no return open platforms work perfectly. Irrelevant to my point.

Companies/Content Creators are on the platform because it pays them. If being on youtube did not pay them, they would go to a platform that did, eg twitch, tiktok.

Peertube doesn’t give ad revenue sharing, so most content creators can’t afford to make content for a platform with no return. If someone was uploading a video for their friends, or a school project, then sure, open platforms are perfect.

It is AN answer, but also not the only answer. Generating and moving power around is extremely complex and just seeing “Solar cheaper per Watt” and defining it as the best in all cases is silly. If you changed the axis to be size per MWh, then you would draw a totally different conclusion.

When you use your “one password” you’re in effect giving your device permission to access the key storage in your TPM to fetch the private key to present it to the site.

Very small correction as I understand, but your private key is never presented. The web service should never interact with the private key directly. Your device is signing some bit of data, then the server uses your public key to verify that it was signed by your private key. Its a small distinction, but is one of the principal uses of asymmetric encryption is that the public key can truly be public knowledge and given to anyone, while the private key is 100% always only accessed by you the user.

Not literally copy, as in have an extra set of keys. A spare key. A bank vault is total overkill. I just bought 2 fido2 keys and register both for the services that support them. Have one on your keychain and another in your desk. 2FA is often way over thought, any adversary needs both factors so something you know and something you own is plenty for most people.

A hardware device is a physical key. Its no different than backing up your home key. Get two keys and copy them. Keep one on you, and the other in a safe somewhere in case you lose the first.
