The first tweet doesn't fit into the title bar. It says

"Can you believe that we employ someone to print out data from one database and then type it into another database?"

And the twitter thread is full of people (mostly in healthcare) who are not in anyway surprised this happens, or who think this is not as complex as some solutions could be.

I'm submitting it because lots of people on HN want to find ideas to work on, and this kind of interoperability is one idea that could be worked on.

Awk is amazing, but they're not going to use awk.
