This comment doesn't understand why CRISPR is such a big deal in science. While Cas-as-a-therapeutic is easy for the public to understand, and therefore often emphasized in popular science, the primary use of CRISPR Cas systems is in modifying genes in the lab.

Tens of thousands of papers have made important scientific advances using it successfully and CRISPR-Cas methods are used routinely throughout almost all of biology.

This is like calling PCR "overhyped" because PCR-based infectious disease diagnostics are limited.
