To my surprise, even sophisticated means of traffic masking like amnezia and vxray get disrupted frequently, requiring hopping around self hosted solutions and updating ones setup periodically. That's waaay beyond what most people are capable of. I am fortunate to have some tech worker acquaintance who live next to my family members, otherwise there'd be no way for me to for example guide them through setup and re-configuration remotely. Still, this setup gets disrupted every month or so requiring manual intervention.
I still consider jax.vmap to be a little miracle: fn2 = vmap(fn, (1,2)), if i remember correctly, traverces the computation graph of fn and correctly broacasts all operations in a way that ensures that fn2 acts like fn applied in a loop across the second dimension of the first argument (but accelerated, has auto-gradients, etc).
