Perhaps cult deprogramming techniques can help woke people. I don’t know anything about them, but it’s worth looking in to .
I didn't realize the "Why balls fall at all" was a button.
Predefined things you can drop are basketball, bowling_ball, massive_sphere, dense_sphere, lead_sphere, pine_sphere, pingpong_ball, ant, rat, cat, person, and phone. You can add other things if you know their mass, cross sectional area, and coefficient of drag.
* `add Plots` on a new temp environment takes about four and a half minutes, most of which is precompilation.
* `using Plots` took 16 seconds, and
* a `plot` call after that is 7 seconds.
For comparison, on 1.6, the times are seven and a half minutes for precompilation, 17 seconds for `using` and 10 seconds for the first `plot`. I'm not patient/masochistic enough to try the same on 1.5 too, but the trend is definitely one of continuous improvement.
This is certainly not the sort of machine any production Julia code will be run in, but it is in the category of machines that a lot of students and many others trying out the language will have access to, so it gives an idea of their experience.
The times on 1.6 and 1.7 have been a qualitative change for me. plot being sub-10 seconds means that instead of it being "run it, switch to something else while I wait (potentially losing my mental context), come back and hope it's done", it's now "run it, stare at my dog for a few seconds, the plot is ready".
I don't think time to first plot is that bad anymore.
Time to first gradient can be bad in Zygote/Flux.
