Hi, i'm new to this forum

Hi, i have some questions:

1) What is the meaning of Y11k? There is an article titled Y11k?

2) Why the future humans have 6 standard genders?

3) Are these genders standards among tweaks and other terragens too?
Splices and Provolves have their own genders or have the 6 standard genders?

Thanks.
