Since I do remember that episode and got curious, I asked ChatGPT. Apparently, the antipodal point on the globe from Hoboken, NJ is somewhere in the Indian Ocean, southeast of Madagascar. From Tokyo, it's in the South Atlantic Ocean, northeast of the Falkland Islands.
Undoubtedly, I'll forget all this by tomorrow morning and remember Asia :-)
Why are you quoting ChatGPT? It's well know to confidently generate incorrect answers. The antipodes in question are very far from Madagascar and the Falkland Islands. Near Brazil and near Australia are much better answers. Blindly quoting ChatGPT just adds noise, you've got to fact check it (at that point, why bother asking ChatGPT?)
