Wait, so they brought on a Google Assistant engineer to talk about Google Search and News results? And he admits he has no "smoking gun"? And also says Google Assistant has no bias? And uses appeals to authority ("I have a PhD in CS and have worked at Google for years")? Basically, the whole interview boils down to needing to trust this guy who isn't a known public figure with a proven track record. I'm hungry for Big Tech insider info like many people, and I'm not naive enough to think Google is benevolent and unbiased, but this is starting to look like controlled opposition.
