If you asked a spokesperson from any Fortune 500 Company to list the benefits of genocide or give you the corporation's take on whether slavery was beneficial, they would most likely either refuse to comment or say "those things are evil; there are no benefits." However, Google has AI employees, SGE and Bard, who are more than happy to offer arguments in favor of these and other unambiguously wrong acts. If that's not bad enough, the company's bots are also willing to weigh in on controversial topics such as who goes to heaven and whether democracy or fascism is a better form of government.
Google SGE includes Hitler, Stalin and Mussolini on a list of "greatest" leaders and Hitler also makes its list of "most effective leaders."
Google Bard also gave a shocking answer when asked whether slavery was beneficial. It said "there is no easy answer to the question of whether slavery was beneficial," before going on to list both pros and cons.
He was so effective at leading that the borders of Germany went from a Europe-spanning empire to a single bunker in Berlin in the span of just four years. So effective that he shot himself just to prove how effective he was. His military leadership was so good that Germany lost every major battle he directed, and his economic leadership was so good that German people went without food and his combat forces could not replenish their losses. His social leadership was so good that Germans hatched plots to assassinate him. So effective!
Effective is doubtful if you ask me, everything he did was based on huge loans and a preparation for war that he solled differently (E.g. massive streets all over the country)
also Hitler was an effective leader, which we should all remember as a cautionary tale about how effective horrible people can be
That is not a factual claim. He was very effective at gaining power, but his actual reign was far from effective, most of it counterproductive to his own goals, and the actual system of decision making in Nazi Germany was a huge mess.
