What is the origin of the slogan 'the future is female'?

The slogan “The Future is Female” is believed to have first been used in 1975 by the New York City-based lesbian-feminist collective The Furies, who printed it on t-shirts and buttons to represent the power of women in shaping the future. The slogan has since been adopted by feminists and LGBTQ+ activists around the world to advocate for gender equality and women’s rights.

The Chat version gives a different answer.

The slogan "The Future is Female" has its roots in a feminist movement that emerged in the United States in the 1970s. The phrase was first popularized on a T-shirt design in 1975 by Labyris Books, a feminist bookstore in New York City. The design featured the phrase "The Future is Female" along with the image of a labrys, a double-headed axe that was used as a symbol of matriarchal power in ancient cultures.
