He wasn't entirely wrong though.
If you listen to his sentiment and then listen to Dr Epstein's podcast on how big tech (in particular Google) is essentially brain washing society with propoganda and can (and has matter of fact) swing elections in recent times in the US.
Dr Epstein came across very well, provided his data matter of fact and supporting evidence of cases he carried out.
As he stated, Google essentially control a good 96-98% of the internet, its very difficult to find balanced information on any topic so it convinces large sections of society into thinking a particular way.
And I mention all this because its obvious Google is arguably the main resource tool people use today to inform themselves on any given topic. When you are not receiving a full and balanced picture of a given subject how can you suggest a person is properly informed?

There are a lot of major flaws in this guy's analysis and I find it a bit hyperbolic and based on a misunderstanding of both Google's algorithms, how people actually behave, and democracy itself. The idea that Google is "brainwashing" is overblown propaganda itself.
First, the goal should never be "balance." It should be accuracy and truth. It's like the conservatives whining about how Google results are "unbalanced" to support climate change. Well, that's because there is an overwhelming consensus on man-made climate change. This fake Fox News imperative to always show "balance" is actually much more problematic. Balance is not some virtue. Do people really need to read dozens of articles from climate change deniers to be well informed? Epstein seems to believe they do. Reality is, they do not.
Second, and this dovetails off the first, it's not that SERPs are "biased to one political party", it's that the sources in questions, say Time, The Hill, NY Times, The Atlantic are simply more trustworthy and reliable sources for information than soures like The Daily Calley, Sputnik News, or The Epoch Times. I've seen conservatives (former friends) whine on Facebook that Google serves them biased results but whenever I look at the example the reality is Google is serving up results that are the most reliable, best fact-checked, and from sites that have the most accountability and will print corrections if they are wrong rather than biased political sites from the right. So it's really not any preference towards bias but a preference towards EAT (expertise, authoritativeness, trustworthiness) and its just a fact that allegedly liberal biased sites like The NY Times are more trustworthy and less biased than The Daily Caller.
I could go on but people like Epstein are frustrating because they know just enough to be dangerous but not enough to really understand what they are talking about. He can't prove manipulation based on looking at results for the very reason I just mentioned. Analysis like Google posting "Go Vote" somehow manipulates the vote unless the end result is somehow 50-50 for each political party is just garbage analysis. And Trump's election itself shows his presumption that "big tech" can allegedly "shift" 15 million votes.
This guy himself is heavily biased and his "research" has been thoroughly debunked across many channels.
“When Dr. Epstein says the effects are ‘huge’ and ‘more powerful’ than anything he has ever seen, I respectfully suggest that he needs to read the political science literature before making that claim,” Katherine Haenschen, a communications professor at Virginia Tech University who studies internet targeting on voter turnout,
told Mother Jones this week. “Large-scale digital mobilization has basically failed to deliver sizable effects in terms of persuasion or turnout.” Never mind the fact that in Epstein’s study, it’s not clear what search terms were used by his participants, or what the “biased” search results were. In his
research, Epstein graded search engines for bias, determining that mainstream news outlets like the New York Times dominated over conservative sources like Breitbart in Google’s results. Epstein doesn’t explain the context in which the searches were conducted—which is important to know, since the whole point of Google Search is that it
personalizes results based on prior searches and the user’s location. Someone with a recent search history about guns in Tennessee will likely see different search results than someone with a recent search history about women’s health care in New York City. And a good study would take care to somehow sanitize or disclose each participant’s search environment before reaching any conclusions."

"Another issue, other academics say, is that Epstein’s study did not establish a link between alleged bias in search results and voter behavior in 2016.
Epstein said he came to the conclusion of bias sufficient to affect 2.6 million to 10.4 million votes based on what he has found in studies of national elections outside the US, including the 2010 Australian prime minister election and a 2014 Indian legislative election.
In other words: Epstein did not test 2016 American voters to see if their Clinton-or-Trump choice had been changed by search results they got. He extrapolated from his previous studies."
