Trade it in, or maybe even just eBay it off.
I had a 2020 Air with i7, 16GB, 512GB and did the trade-in around Christmas for the M1 Air with 8GB, 512GB and it's miles better. Just the fact I don't have to worry about putting it down on the couch, bed, blanket, etc and getting too hot or blocking the fan is amazing. I always baby my gadgets and for once I don't feel like I need to and find myself thus using it far more often. It is so much more responsive than the i7 ultra low power was by leaps and bounds.
If the 14" MBP comes out with an M1/M1X/M2 or whatever, I'll likely upgrade but not because of any shortcomings of the Air.
