Software millionaires are not buying fine art, which worries galleries. But can the art world’s inclusiveness be partly to blame?

Sima Familant, a New York art adviser, said she thought the tech industry had almost an obligation to become more engaged with art.

“If these are our next Rockefellers, Carnegies, Fricks, whatever you want to say in terms of our wealthy American elite, then why aren’t they supporting culture?” she asked.

Ms. Familant, 40, said she worried for the future of privately financed arts establishments.

“If these people are the new wealthy, and they’re not supporting institutions and the arts, then we’re going to have a really big problem at some point,” she said.
