It's really, really not. Just write the libraries yourself. Have a team or two who does that stuff.

And, if you do need a lib because it's too much work, like maybe you have to parse some obscure language, just vendor the package. Read it, test it, make sure it works, and then pin the version. Realistically, you should only have a few dozens packages like this.

at some point having LLMs spit out libraries for you might be safer than actually downloading them.
