I think this argument is quite facile. These people are scientists trying to understand superconductivity at a basic level, and this theoretical research (as well as the experimental results posted on this forum earlier this week) are a genuine advancement in that field. You are judging this research based on how it is directly applicable to making handheld devices with room temperature superconductors when that is not what these people are attempting to do at all. The fact that a superconducting state can be maintained at these temperatures at all is, indeed, "record shattering". We do not have the ability to simply engineer a material that can superconduct at ambient temperature and pressure at will. I don't mean to be to confrontational, but reading the comments on these articles it really pisses me off to see the hard work of actual scientists judged by the rubric of whatever science fiction garbage internet commenters think should be possible.
