Richard Stallman sez we should call it ‘PI’ … pretend intelligence.

I remember Angela Collier talking about this topic, but basically: the “AI” in question is a different beast from the “AI” in chatbots and image generators. The underlying tech is the same (artificial neural networks), but instead of making the bot mimic human output, you’re asking it to point out stuff.

So for example, you feed it with two sets of data:

1. a bunch of pics of completely normal astronomical objects
2. a bunch of pics of anomalous astronomical objects

Then you “ask” the bot to assign new pictures (not present in either set) to one of those sets.

In my opinion it’s one of the best ways to use the new tech. If there’s a false positive, nobody is harmed — the researcher will simply investigate the pic, see there’s nothing worth noting there, say “dumb clanker”, and move on. Ideally you don’t want false negatives, but if they do happen, you’re missing things you’d already miss anyway — because there’s no way people would trial down all those pics by hand.

It also skips a few issues associated with chatbots and image generators, like:

• since it’s “trained” for a specific purpose, it isn’t DDoSing sites for training “data”. It’s all from the telescope, AFAIK in the public domain.
• no massive training = no massive water/energy cost.
• no concerns related to authorship or whatever.

Can we be sure? An ai only knows stuff its trained on?

Wow it’s tiny

Telescope is almost a misnomer here. It will be “looking” at other satellites, not astronomically distant objects.

The influence of gravitational waves will be seen in changes in the relative distance to each of the six satellites.

Yes, but also no.

Each side of the triangular array will measure nearly 1.6 million miles, or 2.5 million kilometers.

The satellites themselves may be small, but the interferometer antenna they’ll collectively form will be huge.

Only 137 light years away. And that’s at the speed of light. It is out of reach to organic life but we might send AI out there
