What a bizarre take

Many people refuse to use LLM's for various reasons that I don't need to rehash here

"Bizarre" is rejecting powerful tools on ... what, religious grounds?

It would be one thing if we were talking woodworking or pottery or another skilled craft, where your personal growth of talent with experience is evident in the product, resulting in something you can look back on fondly and point to with pride.

But moving some legacy code (which you didn't write) from one platform to another? What do you get out of doing that by hand?

You seem either deliberately or functionally unable to grasp the premise of why anyone would do this (or reject LLM's)

I suggest instead you go read up on why people dislike them and gain a more well-rounded and nuanced understanding of the topic

And you seem to be operating on a faulty premise (as was I.)
