Repeating what some have already said here:

• PBS SpaceTime is outstanding, and manages to ride the line between informative and accessible very well. Some episodes especially around heavy math/quantum mechanics are impenetrable for me but all the space stuff is great, the scripts are very well written, production value is top notch.
• Dr Becky provides amazing content mostly geared around recent research and theories - especially with the James Webb Space Telescope being a year old now there’s some amazing insights coming out that she does a great job explaining. A bit less “pseudo lecture” than SpaceTime but still highly informative
• StarTalk (Neil Degrasse Tyson) is great, but in a different way. It’s less formal and very much more like a podcast than a lecture or report as the prior two are.
• Sabine Hossenfelder delivers a periodic “science without the gobbledegook” show that covers all areas but generally has a focus on physics and astrophysics. She’s semi-famous for not tolerating nonsense while also considering a sizeable portion of contemporary physics research to be nonsense. I think she’s hilarious in a parchment-dry German kind of way, and her content goes arguably deeper than the other channels listed here in terms of subject matter - I usually leave her videos thinking about things in a different way.
• SmarterEveryDay is a general science/learning channel but really piqued my interest with a recent video about talking to NASA:

The host has a background in aerospace engineering and missile test flights - so its about as close to rocket science as you can get! He knows his stuff and has a lot more practical, engineering related videos - kind of makes you think about how to operationalise the more cerebral ideas of the other channels.

Hope you enjoy some or all of the suggestions here and from other commenters

I mean if it is its clever - put a bunch of made up products out there to gauge interest without needing to invest any capital, then actualy make the products that garner the most attention. Makes way more sense than trying to manufacture and market things from scratch

I saw one suggestion which was to so away with male and female competitions, and instead have “open” and “restricted” comps. Open would be available to anyone, male or female, while you could set up as many restricted comps as you needed for the particular sport or activity with whatever rules make sense. So the 100m sprint might have Open, Restricted - Testosterone, and Restricted - Height - with whatever T level or height in centimetres decided by the relevant authority. Whereas something like weightlifting might have Restricted - Weight as it’s own class. The idea being any gender can compete provided provided meet the restrictions in place to make an interesting/fair competition within that bracket.

Theres a lot of research going into carbon sequestration through soil and plant technologies - basically accelerating what would happen naturally by a few orders of magnitude.

Rapidly filling artifical peat bogs (through things like algae/weeds that are genetically modified to absorb more CO2) would allow for semi-permanent carbon capture as long as no one digs it up again. Similar projects with seaweed are under research as well.

Personally I think anything to do with carbon capture is a bandaid at best, and failing massive global cooperation and societal change, we’re going to end up needing to geoengineer our way out of the problem. Things that block or impede solar heat absorption to cool the planet - atmospheric aerosols, artificial cloud generation, solar shades out in a lagrange point, basically manipulating conditions to influence how much energy is going into the system. There’s a nonzero chance we fuck it all up but as we hurtle through temperature records and tipping points, the idea of net zero emissions actually having an impact in our lifetimes seems more and more unlikely. There’s too much inertia in the system.

Network security is a pretty big ask though - just look at how many unsecured cameras are around now. And once an attacker is in anything generated on that network becomes suspect - how do you know the security camera feed wasn’t intercepted, manipulated, or replaced altogether?

I envisage a world where your browsing Netflix, and based on past preferences some of the title cards are generated on the fly for you. Then based on what you click, the AI engine warms us and generates the film for you in real-time. Essentially indistinguishable from the majority of Hollywood regurgitation.

And because the script is just a series of autogenerated prompts, its like a choose your own adventure book, you can steer the narrative the way you want if you elect to. Otherwise it’ll be good enough to keep most monkey brains happy and you won’t even be able to tell the difference most of the time.

It sounds like a cursed item in D&D or something.

The Book of Faces Wondrous Item, very rare

This enchanted tome magically records the likeness each humanoid slain in its vicinity, preserving a snapshot of their life and memories. The book can be read to glean superficial information about it’s subjects. As an action, you can tear a page from the book to summon a ghostly spirit of its subject, which will be magically compelled to answer questions. The spirit knows nothing the owner did not know in life.

The Demon Lord Elgor Ithym is said to have a keen interest in this book…

Ooh I know some of this!

Sauron was a Maia (lesser primordial spirit), who along with Morgoth (a fallen spirit formally known as Melkor) was at odds with essentially every other spirit and the general concepts of peace and tranquility that were sought by the creators of the universe. After Morgoth was defeated, Sauron inherited the role of the eponymous Dark Lord and sought to rule Middle-Earth in its entirety.

The Wizards were the Istar, a group of Maiar tasked by the Valar (greater spirits) and Manwe (the king of the Valar) to travel to Middle-Earth and aid the Free People in their fight against Sauron. They took the form of elderly men and roamed the lands to counter and subvert Saurons influence. Their mandate prevented them from open conflict, which is why they took on the role of advisors and supporters instead of just fighting Sauron head on or rallying armies to fight him. Their origins were unknown to any of the Free People, but the Elves for sure new that they weren’t just Men - since they lived for thousands of years and had gifts that no mortal Men possessed.

Bombadil is likely another Valar, off in Middle Earth doing his own thing - in ancient ages many of the Valar visited or lived in Middle Earth, so it could be that he didn’t return to Valinor and just hung around. His complete disinterest in intervening in the conflict is one clue, and the fact that he exceeds Sauron in raw power as the One Ring is completely mundane to him, whereas Gandalf fears that it will overpower him, is another.

Thats insane, in Australia at least it’s still just a data plan - buying a cheap prepaid SIM or mobile plan for data is a common thing since our Internet infrastructure is shithouse. I hope no aspiring telco middle managers cotton on to this.

This is a good summary; as a reddit exile myself who exclusively used Sync, I think it’s worth emphasising that Dawson has done an amazing job of making the transition from reddit to lemmy pretty seamless from an app design point of view. I can set my views and filters up identically as they were in the Reddit version of the app, and the lemmy experience becomes essentially identical to reddit.

There’s definitely a conflict between “paid closed source app” and “FOSS fediverse”, and there’s arguments to be made about whether user revenue should be directed to server expenses to maintain communities or front end app development to attract more users, which I think will be interesting to see play out. But at the end of the day Sync makes lemmy “useable” in a way that replicates the reddit experience, which is what a lot of migrants were after - other apps (while arguably more feature rich in terms of the fediverse) just didn’t quite hit the dopamine-feed the way Sync does.
