WebJan 1, 2024 · According to Harris, Lightmatter, which was founded in 2024, has so far hired at least 100 employees—including Richard Ho, who led Google’s development of the Tensor Processing Unit. Harris adds that the company has also raised more than US$115 million from top venture-capital firms, with “more on the way.” WebCredit: Glenn J. Asakawa / University of Colorado. Ongoing advances in electronics and computing have introduced opportunities to achieve things that once seemed inconceivable: build autonomous machines, solve complex deep learning problems, and communicate instantaneously across the planet. Yet, for all the advances, today's systems—which ...
