Rapid progress in gene editing is being made but there is still a lot to learn.

We know enough now to be really dangerous. 20-30 yrs from now this will all be trivial and easy.

There was recently the editing of human fertilized cells and embryos. The cost of actual CRISPR gene editing was as little as one hundred dollars. The far greater costs are the many gene sequencings before and after to ensure that the correct change was made.

The learnings needed are not just that changing one gene or multiple genes has particular desired effects but also what unintended effects occur.
