Why are we focused on a room temperature superconductor instead of a less cold superconductor?

As I understand it, superconductors work best at temperatures approaching absolute zero (-273.15C). For example, Google tells me that the superconductor in an MRI operates at -269C.

There has been a lot a buzz lately about room temperature (25C) superconductors being discovered, but why is room temperature the focus? Why not focus on superconductors that work in reasonably cold environments? For example, we can easily get temperatures to -15C in a freezer. Why not create superconductors that work in that temperature range rather than 25C?

That’s it.

Rule 5- No baiting or sealioning or promoting an agenda.

Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.

Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

Rule 10- Majority of bots aren't allowed to participate here.
