Packed house for the @openlakehouseai Meetup earlier this week at @databricks.

@lukekim joined Shawn Chang, Haoyan Geng, and Lisa Cao for a wide-ranging discussion on the current state of the data and AI landscape, and how data infrastructure needs to evolve to support the next wave of enterprise adoption.

The future is open! Thanks to Databricks, Scott Haines , and Yufa Li for bringing together the community.
