  > So what does the transpiling get you in that world? You can already run the old code on modern hardware (per tfa) and you already have people who understand the existing assembly to help do a rewrite... Basically what the ancestor comment enumerated. It basically allows for a more conservative and incremental approach to rewriting things, since it would give you the ability to mix old and new code. It seems like they plan to do some parallel testing, but if they used the transplier (and it was correct), they could probably do that at a much lower level (e.g. run both functions in parallel in PROD but only use the "old" functions results, log any discrepancies, you know you're done when there haven't been any for a while).
