Is that level of precision even remotely achievable with today's technology?
My understanding is that orbital insertion accuracy is in the ±10-50 meters range, with the most advanced formation flying satellite swarms hitting 10 cm to 1 m precision between satellites with the help of optical navigation.
But the precision between the panels on a telescope like JWST is in the sub-mm range, no?
Also, I'd assume stuff like orbital decay, atmospheric drag, gravitational perturbations, and solar radiation pressure would make it difficult to maintain precision over time.
I'm sure/hopeful there's some people here at HN working on stuff like this, please fill in and correct me!
You're only buying eggs every second week? We can't have that, let's present you with a recipe that uses eggs. You still have those cookies you bought four days ago? Let's give you a coupon for milk.
And there will be a nice recipe or a coupon or a Very Limited Exclusive Offer you'll need to send to a friend, so now the app need access to your contacts, and why not sync that info with Meta, and oh look at that, we have a map of all our customers and their spending habits and geographical location and political orientation.

What in the Orwell
When Nielsen first started collecting data (1950s), they handed out diaries to a group of around 5 000 selected households. Nielsen would then collect these diaries and extrapolate viewing patterns across the entire population.
After that came phone surveys. Next step (1980s) was the "people meter", a small box attached to the TV that could automatically detect which channel was tuned and which household members were in the room.
In the 1990s the set-top box made all of that redundant as the cable and satellite providers could directly see which channel every single box was tuned to at all times.
MacBook Air -> MacBook Air 2: unibody aluminum construction replaced plastic, ssd option introduced.
iPad -> iPad 2: cut thickness and weight by 30 %. A4 -> A5 doubled performance. Dramatically better screen. Introduced the magnetic case ecosystem.
iBook G3 -> G3 dual usb: from colorful clamshell/toilet seat design to sleek laptop. 30 % lighter, half the volume, twice as durable, 2-3x the performance.
And… Apple I -> Apple II? Apple I was a motherboard, the II was a complete computer.
Also, from a practical standpoint, charging some and not others is not necessarily better if the selection is made politically. That moves the needle from "at least something got done" to "law is just a tool of oppression".
ESPECIALLY the evolution of macos and ios.
