Sure it is now, but it was not always. Gentoo didnt just spring forth from the aether full-grown.

pre-alpha

The period of pre-0.1 that I reference above, ended in 2002 with the release of 0.1 Alpha. This is back when the idea of adding a binary installer was controversial in the gentoo community. That was 24 years ago, in case you are following along. So going on about the current state of Gentoo is not super relevant. I am glad it is better, but I am old enough to remember when it was a pretty gnarly ball of yarn and that is what I mentioned.
