thanks for suggesting those alternative packages. I understand that there are many alternatives. My choice of Zygote was that this was going to be the future of AD and I cannot afford to invest in something that will be replaced in a few months.
But then I just learned that Zygote will be replaced with something called Diffractor?
So what should I be investing in? Will I be relatively safe if I focus my development around ChainRules and use Zygote or any of these others only sparingly?
