Recently have been reading the Gene by Mukherjee. I'm amazed at what had been accomplished in the mid 20th Century. A lot of what still seems crazy now was done already albeit in small scale.

Growing new appendages is clearly much more involved, but a Youtuber was able to give themselves lactose tolerance for a couple of months (they were lactose intolerant before). Assuming it wasn't faked for views, and that we are what we eat, that suggests other modifications to gut bateria aren't inconceivably far off.

Unfortunately biology only does spaghetti code.
