It's understandable. Science journalism exaggerates results, even if the original researchers and their paper did not. And even the most promising scientific results can take decades to be applied in the industry and become available to consumers.
But at the same time, this is Hacker News, not Mature Consumer Product News. Here is the best place to discuss what tech in 2030 might look like, not what we can buy today.
this might be true for certain graphene stories (or paid advertisements where it's covered up who paid for those) but please don't say that "journalists" (meaning the whole group of journalists) have "zero morals". Because (real) journalists at least report more or less about the information that they receive and (yes) interpret it, that's better than zero morals (how much can be argued). Zero morals are what you find with certain politicians (or social media users or paid-for-studies-by-cartels) that pull their stories out of their behinds with no accountability whatsoever. Journalists still have a certain higher standard. And we shouldn't neglect this or say otherwise because this would lead to further erosion of trust in media. People should trust news sources more than social media posts because real news sources are still (!) more trustworthy than social media posts. Critical reading and thinking for thyself should be on the agenda everywhere, though.
