At the very least this will revolutionize genetic research. Many of those errors will cause a shift in the genetic sequence that essentially ruins to code, effectively turning off the gene. This is sure to be another boost to genetic research, perhaps as big as CRISPR itself. Genetic research has been progressing at a geometric, not linear, pace for the last half century at least. This is partly because our increased understanding of genetics improves the technology of genetic research itself, so there is a positive feedback loop.
