This data center is not that.

The infrastructure of the AI economy is being built by a lot of different companies.

CoreSight is what's called a co-location provider.

All kinds of businesses, banks and social media platforms and hospitals.

You do not have here in Los Angeles, certainly a low cost of real estate.

You do not have a low cost of power.

Oh, and it's hot, too.

It's really hot.

It's really hot.

This is an operational computer room.
