Hi, yes, I’m here. The user. Of both, in fact.
Both Bluesky and Mastodon have their quirks and their different cultures. The feature sets of their protocols may also be different, but they sure aren’t relevant to the experience at all, because federation is not a user-facing feature for the vast majority of the social media experience.
Stop cheerleading for social networks. Social networks are not your friends, including Mastodon or the rest of the “fediverse”.
I rip enough physical media to tell you that post-compression 14GB is not far from average for a 4K movie. I guarantee that Netflix isn’t storing those any bigger than that. Hard drives don’t grow on trees, you know?
It’s still good to know where the top end of optical storage is, even at an academic level, even if these end up not being widely used or being used for specific applications at smaller capacities. We’ll see where or if they resurface next, but I’m pretty sure we’re not gonna get femtosecond lasers built into our laptops anytime soon.
