"Funny opinions in our country: When a German general manager is actively orientating his company towards the future, he is considered arrogant and too philosophical. When a grass smoker colleague from the United States talks about Peterchen's trip to the moon, he is an admired visionary, ”Kaeser wrote, referring to a German children's story about space travel.
Siemens declined to comment on the tweet, which was published a few days after the group's deputy general manager, Roland Busch, who is German, described Musk as a visionary.
Kaeser's statement sparked heated discussions on social media, with Siemens managing director later wanting to clarify his comments.
In an exchange of answers with a journalist from an economic publication, Kaeser said in a tweet on Saturday that no speculation and effort is needed to link Busch's remarks to Musk.
"It's not about Mr. Busch and / or Mr. Musk, ”Kaeserm said, adding that his goal was to draw attention to the entrepreneurial spirit in Germany and the declining importance of German companies.
Last year, Musk caused a storm on Twitter after he smoked marijuana during a live webcast of Joe Rogan.
In September, Siemens promoted Busch to the position of deputy general manager, becoming a favorite for Kaeser's replacement at the helm of the engineering group.
On October 31, Busch wrote on Twitter: “It was great to meet Elon Musk, a true visionary of our times. We talked about the future of mobility, the rapid introduction of car charging stations, electric mobility, advanced production and rocket engineering. We are proud that Siemens technology supports Elon's most exciting dreams. ”
At this week's annual Siemens press conference, Busch said that Tesla and SpaceX, the automaker that builds rockets, are big customers of Siemens.
