Itโs a question that keeps many of us up at nightโand for good reason.
Our new research maps labor market vulnerability in the age of AI with 100K job postings and 50K AI-related patents. (1/5)

To track this, we developed the Weighted AI Index (wAII), a scalable method to measure how closely a jobโs tasks align with recent AI innovations.
We extract key job tasks from postings; compare them to AI-related patents; compute an โAI exposureโ score. (3/5)

Hot takes:
- The benefits of easily accessible social media data usually outweigh the potential harms.
- Some uses of (public) social media data are unethical/should be illegal, and we should target that.
- We're better off having clear boundaries between public and private online spaces.

FYI, here's the entire code to create a dataset of every single bsky message in real time:
```
from atproto import *
def f(m): print(m.header, parse_subscribe_repos_message())
FirehoseSubscribeReposClient().start(f)
```

Just realized BlueSky allows sharing valuable stuff cause it doesn't punish links. ๐คฉ
Let's start with "What are embeddings" by @vickiboykis.com
The book is a great summary of embeddings, from history to modern approaches.
The best part: it's free.

If you're keen to learn content verification for fact-checking and open source investigations, this is a step-by-step guide on how to verify images and videos that I posted a while ago.
Once you familiarise yourself with reverse search, you'll become much better at spotting online misinformation.

THREAD: How to verify online images
Social media is awash with false or misleading images, some of which get millions of engagements.
So here's a simple guide on ways you can quickly check the veracity of images you see on your social media feeds with major elections coming up this year.
