“Futures Past,” a CGI-heavy survey of abstract imaginaries opens at London’s arebyte. Contributing esoteric artifacts and “excavated ruins” of distant and fantastical futures are artists including Morehshin Allahyari, Lawrence Lek, and Kumbirai Makumbe. Contributed works include Juan Covelli’s GAN-generated Speculative Treasures (2021, image), and Sandrine Deumier’s Beyond Matter (2022), an XR tableau of “animal orchids and mineral matter in expansion.”
