Not a coder but I grasped enough.

Lastly, I'd like to know where the AI got the idea from. Sounds like pizza glue.

I don't think this is a very interesting article. We already know AI suggests nonsense a lot of the time. That in no way demonstrates that it is net-negative. In my experience it's a net positive even accounting for the times it gets things wrong.

Yes you do have to review its code closely. News at 10.

It is kind of funny that they picked an example where it made an obvious mistake for their hero image though.

let mut bytes = vec![0u8; len as usize];
    buf.read_exact(&mut bytes)?;

// Sanitize control characters
let sanitized_bytes: Vec<u8> = bytes.into_iter()
    .filter(|&b| b >= 32 || b == 9 || b == 10 || b == 13) // Allow space, tab, newline, carriage return
    .collect();

This implicitly, and wrongly, swaps the interpretation of the input from UTF8 text to pure ASCII.
