coffee, the same voice might mean the same just an octave apart.
Sam2, the Gemara in Sanhedrin says that it won’t be because it doesn’t make sense to happen that someone should get punished for eating and drinking.
Am Yisroel,
The same place that the Gemara makes that statement that it will never happen, it answers your question: Lehagdil Torah Ulehaadira. It is a Mitzva to learn Hashem’s ways, whether it will happen or not.
Additionaly, one Amora said that he saw the grave of a Ben Sorer umora and sat on it. The Maharal explains that although there won’t be an actual Ben Sorer Umora, the concept exists. When this Amora said that he saw the grave of a Ben Sorer Umora, he was referring to Yerushalayim, which was treated by Hashem as a Ben Sorer Umora. They were exiled before things can get any worse.
ALso, Chazal actually say what the Parsha of Ben Sorer Umora is doing there. It says that if you will marry a Yefas To’ar, you will end up hating her and will end up with a Ben Sorer Umora. Obviously, they aren’t referring to an halachik Ben Sorer Umora, but to a child that will rebel. Avshalom Ben David was the son of a Yefas To’ar.
