Seems pretty dumb in our biological design to not be able to regenerate such a functional (and also easily breakable) part of our body.

      The downside could be something that nobody has imagined yet. That is the problem with change. I’m not against this, but I demand reasonable study. (but not unreasonable levels - vaccines and GMO have been studied enough to conclude they are generally safe despite people yelling more study needed)
