SAN FRANCISCO — If you have sent email on Google or used Microsoft’s browser or databases, you have touched the technology handiwork of Adam Bosworth.

Mr. Bosworth, a tall and grizzled but still trim 60-year-old, is a Johnny Appleseed of sorts in the tech industry, with a penchant for being intimately involved in the creation of generations of widely used technology.

While it is never easy to predict what the next big thing will be, identifying what Mr. Bosworth is working on is always good for clues. Right now, along with competitors at companies like Amazon and Google, he is building what some call a “data singularity.”

Imagine if almost everything — streets, car bumpers, doors, hydroelectric dams — had a tiny sensor. That is already happening through so-called Internet-of-Things projects run by big companies like General Electric and IBM.
