But Julia and Python tools aren't enough. The whole environment has to be reproducible. So many python libraries themselves take shortcuts which work on the current Ubuntu or current state of the web, but will fail to build later by the time someone tries to reproduce the result. Shipping a container just hides the implicit dependencies and assumptions. People need to be packaging for Guix en masse for reproducibility to be feasible. Until then, "reproducibility" is just another lie people are telling themselves and others to try and get ahead in their rat races.

So you say "julia and python tools aren't enough" but then proceed to only talk about Python and say a bunch of stuff that is completely inapplicable the Julia.

Do you know much about how reproducibility is approached in Julia? Maybe hold off on calling it a lie if you're not experienced in what you're talking about.

I have asked about Julia's reproducibility story on the Guix mailing list in the past, and at the time Simon Tournier didn't think it was promising. I seem to recall Julia itself didnt have a reproducible build. All I know now is that github issue is still not closed.

"reproducible build" in this sense has nothing to do with scientific reproducibility. That issue is about hash-verifiability for the sake of security, and how some autogenerated random paths included in the binary affects that.

Scientific reproducibility requires only that versioned binaries be functionally equivalent if they have the same version, which is quite independent of this and certainly exists in Julia.

Would love a link to the Guix mailing list discussion, if you can dig it up.

I agree with your first sentence, but saying people are fooling themselves and being overoptimistic (by telling themselves lies) is very different from "calling it a lie" (i.e. intentionally deceiving others). That seems like an unnecessarily negative interpretation of what they said. Even if you disagree with it, that does not deserve such a harsh response.
