A half life of 2×10^19 years still means 100 events per gram per year, 100 new defects in the chip every year.
I'm not a material scientist but I'm not sure every single atomic decay will result in defect
Every decay will result in at least one crystal defect. Alpha particles don't travel very far, so it probably cause another crystal defect nearby, and maybe a short chain reaction. I'm sure they can work around it but I don't think it will be easier to deal with than the defects due to ion migration they already have to deal with in Silicon.
