If you've seen the headlines — data centers as economic savior or neighborhood villain — but weren't totally sure what a data center actually is, this episode is your starting point.

Aicila sits down with John Bowman, an IT veteran with 35 years in the industry, to trace the arc from the very first data center (built in 1945 to house ENIAC, a military computer the size of a room) to the cloud infrastructure powering your phone right now.

In this episode:

• What a data center actually is — stripped of the hype
• From military origins and DARPANET to corporate mainframes and the dot-com era
• How Amazon Web Services and the iPhone arriving at the same moment changed everything
• Why cloud computing democratized access to computing power
• The basics of how data centers work: power, cooling, fiber, security, and fire suppression (including why John had to practice escaping his rack in under 10 seconds)

The BiCurean thread: Before we can have a real conversation about what's happening now, we need to understand that data centers didn't appear with AI — they've been quietly running the world for nearly 80 years.

Next episode: AI arrives, and things get complicated.
