Additionally, media speculation of contemporary figures as being on the autism spectrum has become popular in recent times. "New York" magazine reported some examples, which included that "Time" magazine suggested that Bill Gates is autistic, and that a biographer of Warren Buffett wrote that his prodigious memory and "fascination with numbers" give him "a vaguely autistic aura." The magazine also reported that on "Celebrity Rehab", Dr. Drew Pinsky deemed basketball player Dennis Rodman a candidate for an Asperger's diagnosis, and the UCLA specialist consulted "seemed to concur". Nora Ephron criticized these conclusions, writing that popular speculative diagnoses suggest autism is "an epidemic, or else a wildly over-diagnosed thing that there used to be other words for." The practice of diagnosing autism in these cases is controversial.
