The pro side always starts with "but think of the diseases we could cure!" And yeah, that sounds noble. But editing embryos isn't just curing disease — it's opening a door we can't close. Once we're okay with tweaking genetics to remove a disorder, it's a short walk to picking eye color, height, or IQ. And let's be real about who gets access to this. It'll be rich people first. Always. We're talking about creating a genetic caste system where the wealthy buy their kids advantages that the rest of us can't afford. That's not a medicine problem, that's a social justice nightmare. Plus, the science is way too young. We don't fully understand how genes interact. One edit could fix a disease but cause something worse down the line, and that mistake gets passed to every future generation. That's not a gamble we should take with real human lives. Some doors are better left closed.

You talked about religion being a human invention, but that doesn't really speak to whether we should edit embryos. Even setting aside the ethics entirely, the practical problems are enormous. This technology isn't just about curing disease. It's about redesigning humans, and once we start, there's no stopping at the "responsible" line. Today it's a genetic disorder, tomorrow it's height, then intelligence, then who knows what. And it won't be equally available either. The wealthy will use it to give their kids advantages that lock in inequality for generations. That's not science fiction, that's just how every expensive medical breakthrough has worked so far. Also, the science is still too immature. We don't fully understand how genes interact. A single edit could have unintended consequences that don't show up until decades later, and then it's baked into every future generation. That's a gamble with real lives, not a lab experiment. I appreciate the goal of preventing suffering, but this is the wrong way to get there.
