Chief Scientist & Senior Vice President of Research, Nvidia

Search every verified William Dally interview, podcast appearance, and on-the-record quote — each transcript cross-checked by AI and human review to confirm speaker identity. William Dally, Chief Scientist and Senior Vice President of Research at Nvidia, gave a keynote at GTC Taipei in May 2026 where he discussed the economics of AI factories, stating that tokens "are now profitable units of revenues" and that compute demand in Taiwan has "skyrocketed" as a result. He estimated the cost of a single gigawatt-level AI factory has risen from $30 billion to between $60 and $100 billion, and argued that "compute is revenues" and "performance per watt is your revenues," cautioning against choosing architecture solely on chip cost. Dally also said the number of software engineers is increasing, describing claims that AI reduces jobs as "complete nonsense," citing the productivity gain of $3 trillion worth of software engineer salary generating $9 trillion in output. In a June 2026 lecture at the National University of Singapore, Dally attributed the deep learning revolution to GPU hardware enabling algorithms and data that had existed for decades, and stated that progress remains "gated by how fast a GPU is." He contrasted Nvidia's product development, where "it has to work or we're going out of business," with Nvidia Research, where the ability to fail allows for innovations that can achieve "2x or 4x performance per unit energy on the next generation." He also referenced an earlier 2020 talk where he described a 317x increase in single-chip inference performance over eight years, a trend he termed "Huang's Law," and credited specialized tensor core instructions for allowing GPUs to achieve efficiency near that of dedicated hardware.

Notable quotes

“I also kind of disagree with the assertion that we're running out of data. I feel like there's an awful lot of data in the world that is not yet being used to train these models.”

“A lot of people think GPUs just appeared and everything was fine, but GPUs didn't just appear — fundamental work on parallel computing and stream processing laid the groundwork, and those ideas (and the students trained by government programs) were essential to building many American industries.”

“The average productivity improvement at NVIDIA using deep learning is about 3x, both on the hardware and the software side.”

“We do some accounting here ... was really only about 3x across this entire 12‑year period. And you know that really shows that Moore's law is over — we're not getting very much from better process technology.”
