  • You do realize that age is not a perfect proxy for mental competence? A good number of people remain mentally sharp well into their 90s, while others experience rapid dementia as early as their 60s.

    I’m not saying his age wouldn’t be a talking point, but I’m damn sure Bernie could express his platform with more clarity and vitality than Biden at this point. Unfortunately I dont think it’s a real possibility, but it’s stupid to act like the the actual birth date matters. It’s the signs of cognitive decline that are problematic.


  • I dunno what that guy was thinking, but it seems obvious to me that nuclear fusion is the long term solution for energy generation.

    Nuclear fission not so much, but it’s definitely debatable which has more fundamental flaws between fission and wind/hydro/solar. All renewable energy sources ultimately depend on natural processes which are not reliable or permanent. And they also tend to disrupt the environment to some extent.

    Nuclear fission has no such limitations, but instead trades long term risk for short term stability. Basically renewable sources are and always will be somewhat unreliable, and Nuclear fission is the least bad reliable energy source to pair with the renewables. So in the medium term, fission makes a lot more sense than fossil fuels, and in the long term we should be looking to fusion.













  • If you ran afoul of a moderator, sure, you could create another subreddit with a name like r/xyz_2 or r/xyzAnarchy. But it would only ever be an alternative, it could never replace the original community, partially because the name was already reserved.

    More importantly, if you ran afoul if an admin, there was nowhere to go. The reddit admins exercise absolute control over the content that is allowed on that site. On Lemmy, people will just leave the server if the admins pull a spez.


  • You just have to choose the right instance. Federation does address those problems.

    Right now our options remain limited because its still early days and the platform isn’t large enough yet. But in the long run, whichever servers do a good job of limiting extremism without being overly authoritarian in moderation will continue to thrive and grow, and servers where the admins are petty and/or politically biased will slowly die.


  • NYC is a bad example because it’s an extreme outlier in terms of size and density. But the metropolitan area is actually much larger than the urban area; here’s a map of all the counties within the NYC metropolitan area.

    It covers 8,200 square miles, just slightly less than the area of New Jersey.

    Metropolitan areas are quite large and typically include the core city along with the entire surrounding area that is economically and culturally heavily linked with the core city.

    https://en.m.wikipedia.org/wiki/Metropolitan_statistical_area

    Here is a map of all the metropolitan and micropolitan statistical areas (MSAs) in the US. Micropolitan areas are essentially defined the same way, except the core urban area of a micropolitan area is <50,000 population, while a metropolitan area has a core city of >50,000 population.

    You can see that metropolitan areas include vast areas that are not even remotely urban. Beyond that, there is also a category called the Combined Statistical Area, which often combine multiple metropolitan areas.

    Here is a map of LA where the red areas are urban areas, the beige counties are part of the Metropolitan Area, and the yellow counties are part of the CSA.

    Greater LA

    The CSA for LA is a whopping 34,000 square miles, or slightly larger than the island of Ireland or the state of South Carolina. However, it only contains about 2,300 square miles of urban area. Estimating the urban area is even more of an imperfect science than the metropolitan area, so I’m not sure how they calculated that number.

    When people say Greater Boston or Greater Toronto, they are usually referring to the MSA, but might also be referring to the CSA. So the short answer to OP’s question is that “Greater” and “Metropolitan” are roughly synonymous. FWIW, I think that metropolitan areas used to be significantly smaller and more urbanized, but they had to modify the definition over time due to trends of suburbanization and decentralization in American city development.
