IBM PC 5150 (1981)
IBM released the 5150, bringing computing to offices and homes. For two decades, computing had run on centralized mainframes operated by specialists in climate-controlled rooms. The PC put that power on individual desks for roughly $1,565.
PC clones flooded the market within a few years, and personal computing became the dominant paradigm.
The shift from centralized to local computing created the software economy built around Microsoft and Intel, reshaping the entire industry.
Portable Computer moves AI agents from cloud data centers to local hardware, a similar architectural reversal. Where the PC made computing local, this makes AI agent execution local, with the cloud reserved for hard cases.
