Bioéthique et génie génétique : enjeux du CRISPR-Cas9

Analyze the rapid evolution of genetic engineering. Write an argumentative text (150-200 words) discussing how the progress of CRISPR-Cas9, characterized by an exponential growth function $P(t) = P_0 \cdot r^t$ (where $r > 1$ is the innovation rate and $t$ is time in years), challenges international bioethics. You must compare the medical benefits, such as treating $Cystic \ Fibrosis$, with the risks of germline editing. Address how the inequality factor $I = \frac{Wealth_{high}}{Wealth_{low}}$ might lead to a biological class divide.
