  • What matters is the outcome

    If that were true, then anyone with any sense would have recognized a long time ago that deterministically incorrect is a lot more valuable than nondeterministically correct occasionally, and given up on all this language model nonsense.

    A deterministic system that produces wrong output can be fixed. A nondeterministic system that produces wrong output cannot be fixed in any way that can be demonstrated conclusively.

    Nondeterministic software is basically worthless in any case where accuracy or reliability are required.





  • Hmm, there’s no discussion of what the energy density is compared to lithium-based battery chemistries. In articles about new battery designs, that usually means it’s pretty bad. This will have limited value if you need 10x battery volume/mass for equivalent energy storage, primarily only for grid-scale systems, which the article specifically mentions near the end:

    The development arrives as the international race to develop iron-based flow batteries accelerates, with the technology increasingly viewed as the most viable successor to lithium-ion for large-scale grid storage.

    I’m guessing these batteries are heavy and bulky compared to an equivalent LiPo. Probably safer than the molten sodium grid storage systems, so that’s good.

    On the other hand, while lithium may be trading at 80x the price of iron on the market, you’re going to need a lot more iron than you would lithium for each unit of equivalent energy storage, plus it’s going to take up more space (real estate). The eventual storage system will probably be somewhat cheaper than an equivalent lithium system, but won’t fit everywhere, especially developed urban areas due to larger space requirements, and definitely won’t be 80x cheaper, even if the iron/lithium price ratio remains the same. It won’t replace lithium batteries in mobile applications (vehicles, electronics, etc) or anywhere that physical space is at a premium.

    The article is written to sound overly positive about this protoype, with a sensationalized headline, while not mentioning the drawbacks, and just hoping that the reader is to too ignorant to notice.

    *Edit: Also, the picture attached to the article is bunk. Flow batteries require a pumping system to circulate the electrolyte fluid, which comes with a long-term.maintenance cost:

    […] all flow batteries include auxiliary components such as pumps and valves, which do require a regular maintenance cycle.

    I don’t know man, prepping to run a session can be a lot of time and effort. Between the rapidly rising cost of living and the very troubled job market, if someone can help pay their bills by DMing a few sessions I don’t see a problem with it. People need to eat.

    I think there’s a lot of demand out there right now for more human entertainment. A TTRPG is a lot more personal than playing a video game, and people want that, but not everyone has a friend group that includes a DM.

    I think a lot of what is currently happening is a consequence of the COVID years. People were isolated for long periods, and a lot of small businesses that provided social meeting spaces collapsed. Post-COVID, people want to go back to socializing but so many local restaurants and other such places shut down, and it seems like habits changed too. People don’t go out as much as they used to, and there are fewer places to do it, so it’s a lot harder to meet new friends as an adult.

    At the same time, a lot of people lost their jobs and didn’t get them back. They had to find other ways to support themselves and their families, and the rising popularity of D&D in particular (I think largely due to content on YouTube from Critical Role &etc) has created an opportunity for that.

    The TTRPG space is changing for sure, and it’s growing. I can tell by looking at the shelves in my local game stores, there’s more and more books for non-D&D RPG games. Plus, there are groups like Legends of Avantris who are now producing their second D&D module, for which they’ve hired a bunch of artists, musicians and other creative people to help with.

    I don’t have a problem with the idea that the growing popularity of roleplaying games is producing more opportunities for writers & artists &etc to make a living.
