  • You can look up what the acronym AESA means without unstanding it.

    Take two speakers that are next to each other. If they emit a tone of the same frequency, the sound will “add up” and be louder in some directions, and cancel out to some degree in others.

    A phased array radar uses the same concept, but now on electro magnectic waves, instead of sound waves. And with much more than just 2 emitters. By carefully choosing the phase of the signal in each emitter, itnis possible to both choose a single direction that receives the strongest signal, and to tighten the spread around that direction (creating a pencil beam). This is what the dish is for in standard radars.

    If these phases can be fully controlled electronically, you can steer where you are looking, and swap between wide and narrow search beams in an instant. However, that is not a trivial thing to produce. So cheaper phased array radars use mechanical systems, or partial electronic steering (example: only horizontal steering).





    1. Threads federates
    2. Threads hosts 99% of all content and all users.
    3. Threads releases and update that allows a new feature. Example: they add buyable threads gold, that you can reward to a post or comment.
    4. The rest of the fediverse can’t implement this feature, and is inherently left behind in terms of features.
    5. Threads releases an update that breaks federation. 99% of the users do not notice.
    6. It takes Threads 3 months to fix the issue.
    7. Go back to step 5.

    Every non-Threads participant will have less features, and is constantly struggling to keep up with the changes and bugs of Threads. Result: the fediverse cannot grow. Only the most stubborn anti-Meta users will accept the objectively worse experience, just to avoid using Threads. But the average user will just use Threads, instead of joining Mastodon, Kbin, Lemmy, or any of the many other fediverse instances that Threads can federate with.









  • New users will look at lemmy.world before they create an account. They will choose to join after seeing threads posts and comments on the front page. The default settings will keep them looking at threads untill they figure out they can block it. But when they do, they realise that 90% of all posts and comments came from threads, and they just disabled most of the content.

    I would be ok with an opt-in mechanism, where the default settings and the anonymous settings disable threads content, but you can unblock them.
