What do the geneticists say we already have built in?

In the context of geneticists and the discussion around genetics, the assertion that we already have built-in imperfections reflects the understanding that every individual, regardless of their genetic makeup, has inherent variations and flaws within their genetic code. Imperfections can refer to mutations or genetic variants that may not serve a beneficial role and can lead to increased susceptibility to diseases or other health issues.

This perspective emphasizes that while genetic engineering and selective breeding can enhance certain traits, it does not eliminate the imperfections that are naturally present in the human genome. These imperfections are a natural part of genetic diversity and evolution, contributing to the complexity and adaptability of the species. Ultimately, recognizing our imperfections underscores the reality of human biology and challenges the notion of creating a "perfect" human, a central theme in the narrative of GATTACA.
