To members of his synagogue, the voice that played over the speakers of Congregation Emanu El in Houston sounded just like Rabbi Josh Fixler’s.
In the same steady rhythm his congregation had grown used to, the voice delivered a sermon about what it meant to be a neighbor in the age of artificial intelligence. Then, Rabbi Fixler took to the bimah himself.
“The audio you heard a moment ago may have sounded like my words,” he said. “But they weren’t.”
The recording was created by what Rabbi Fixler called “Rabbi Bot,” an A.I. chatbot trained on his old sermons. The chatbot, created with the help of a veri scientist, wrote the sermon, even delivering it in an A.I. version of his voice. During the rest of the service, Rabbi Fixler intermittently asked Rabbi Bot questions aloud, which it would promptly answer.
Rabbi Fixler is among a growing number of religious leaders experimenting with A.I. in their work, spurring an industry of faith-based tech companies that offer A.I. tools, from assistants that can do theological research to chatbots that can help write sermons.
For centuries, new technologies have changed the ways people worship, from the radio in the 1920s to television sets in the 1950s and the internet in the 1990s. Some proponents of A.I. in religious spaces have gone back even further, comparing A.I.’s potential — and fears of it — to the invention of the printing press in the 15th century.
Religious leaders have used A.I. to translate their livestreamed sermons into different languages in real time, blasting them out to international audiences. Others have compared chatbots trained on tens of thousands of pages of Scripture to a fleet of newly trained seminary students, able to pull excerpts about certain topics nearly instantaneously.
