ואמר הדור הארון, “and the next generation will say, etc.” Moses refers to a generation that had not yet been born at the time when this covenant was entered into by the Jewish people.
Ramban
AND THE REMOTE GENERATION, YOUR CHILDREN THAT SHALL RISE UP AFTER YOU, SHALL SAY. For the tribes of Israel in the first generation already knew [the cause of the disaster] for they heard the imprecations of the covenant [and therefore he states that the future generation will inquire into the cause of the disaster].

Ibn Ezra
The future generation denotes both your children and the foreigners who will observe the plagues of the land.
