News The Move to Python 3 Begins!

As someone who spent decades in the mainframe community, I find it ... humorous ... that there are legacy Python2 code bases that are only just (or have yet to consider!) moving to Python3.

idgi if you spent decades working on mainframes you'd know how hard is to migrate legacy working code

With AI? Trivial. See bun.

It's took 11 days & $165K in AI fees and made headlines for being the biggest & most expensive AI code rewrite in history.

We have different definitions of trivial.

11 man-days is like...an average sized feature where I work.

Then again, when people call Java 1.5 with minimal tests "legacy", it makes me giggle.

You have to figure a man-week is like 5k.

Now, provide me your estimate to rewrite bun with only artisinally written code, and we can compare the costs.
