Harvard Arts First Festival from 10 a.m. to 10 p.m. Friday, Saturday and Sunday in and around Harvard Yard. Mostly free.

Hundreds of performers and performances show the breadth of Harvard student and faculty creativity and talent in this annual showcase, starting with a Harvard Arts Medal ceremony to honor author Colson Whitehead (his latest, “The Underground Railroad,” won the Pulitzer Prize) and including music (Silkroad Ensemble members are seen above in a Max Whittaker photo), theater, dance and “Make Art” stations for the public. A 34-page guide and schedule to flip through (but for some insane reason not download) is here. A more traditional online approach is here. A map of filterable events is here.

Puppet Noam Chomsky finds an antagonist in puppet Ayn Rand and meets other puppets with points of view (such as Elon Musk) in a play that uses comedy to address political discourse and the dilemmas that artificial intelligence and late capitalism pose in the Anthropocene Era – for kids, academics and nerds alike – courtesy of Pedro Reyes, the inaugural Dasha Zhukova Distinguished Artist in Residence at the MIT Center for Art, Science & Technology. The work is directed by Meghan Finn and written by Paul Hufker. And, yes, Reyes created this with Chomsky himself. Information is here.

Ruckus Dance’s “Baby’s First Show” at 8 p.m. Friday and Saturday and 7 p.m. Sunday at The Dance Complex, 536 Massachusetts Ave., Central Square. General admission tickets are $20.

After 2.5 years appearing of festivals and split bills, Cambridge-based Ruckus makes its evening-length debut in a four-work show dealing with artifice, the end of the world, loneliness, physical prowess and honesty through “intentionally exhausting and perplexing dances” meant to “provoke conversation and bewilder the viewer, driving audiences to ask questions about the logic of what is happening before them” (with occasional nudity and loud noises). Directed by dance-maker and “anti-choreographer” Michael Figueroa. Information is here.
