The comment was made based on the rumours in the story stating what the new Air 6 would be.What made the statement silly was claiming that the "...M1 air will be the better choice" without even seeing what a new Air might be.
Sure a large discount may make an older version attractive despite the shorter life cycle, but without seeing the size of the discount suggesting that the old version will be a better choice is wrong-headed thinking. Since tech is always advancing, older tech needs solid discounts to be justifiable.
You might be right and the new Air may be a more compelling upgrade than the rumours in this story suggest.
Or I might be right and find that the new Air is exactly the improvements as mentioned in the story. Not worth it for me. Wi-Fi 6E and next iteration of Bluetooth not worth anything to me at this point. You may think otherwise for your use case and that’s fine.
