Microsoft co-founder Bill Gates
When joining the social networking site Reddit's Ask Me Anything on Tuesday, Gates talked about the super-high-speed rail, but he also had doubts about the super-high-speed rail.
For the super-high-speed rail, Gates said that he is not sure whether it is conceptually feasible. In addition, Gates has concerns about the safety of the HSR. He believes that it is difficult to achieve safety, but Gates did not specify why he thinks Super high-speed rail is difficult to achieve safety.
The idea of the super-high-speed rail was put forward by Musk in 2013. His idea was to use a vacuum pipeline to build a super-high-speed rail, and the theoretical speed could reach 750 mph (about 1207 km/h).
Although skeptical about super high-speed rails, Gates is still very confident in electric cars and autonomous driving. He is optimistic about the future of electric cars and autonomous driving.
