The big name behind VirtualReality. Formed VplResearch in 1989 but lost control of it in 1992 to French conglomerate Thomsom CSF. Also works on giving free net access to the underprivileged. He's older now and looks back on what he said a mere five years ago as naive. Go figure.
He's mostly also known for his dreadlocks.
JaronLanier also wrote an interesting essay "One Half Of A Manifesto", available at [1], which objects to "cybernetic totalism". Several replies to that essay from "The Reality Club" (including replies from well-known people like BruceSterling and FreemanDyson?) are at [2].
