Haha! This hits home too hard 😂

I'm challenging the narrative that "A.I." is a multiplier in the hands of experts. I see it being repeated everywhere, but there's no credible evidence.

If anything, an expert sees more problems in the output and spends more time fixing them. "It would have been quicker to write it myself".

Last Thursday we started our summer term with a great session at SiriusXM. Next session is online on the 8th of May:

www.meetup.com/scalabridge-...

We have a few new groups running this term (music, Cats, another web project) as well as the usual foundations / Cats Effect / etc.

Yeah, I agree on this. I think that in the right context, not being mainstream is a blessing in disguise. Of course, that comes with all the obvious consequences, but with the right team, anything can be done

Right. Can you elaborate on what you mean by "mainstream"? To my knowledge, none of the languages with the capabilities that you mentioned can be considered mainstream, according to what *I* would consider a mainstream language.

Sounds like you're talking about Scala 😉

Tried it. It's true.

LLMs don't say "I don't know" when they don't know. Because they have no way of knowing they don't know. Because they don't *know* anything.

A factually accurate response and a completely hallucinated response are the same thing to these models.

Indeed, that would make your decoder work as an anti corruption layer. This is why I prefer the `Option[NonEmptyList[A]]` notation for interfaces that handle inbound flows

Just added slides for my talk "Tagless Final for Humans" to my page of talks:

noelwelsh.com/landing/talks/

I gave this talk today at @scalar-conf.com. The core is a new encoding for tagless final in Scala, which makes much better use of Scala's features than the standard encoding.
