????埃倫?穆斯克最近讓他的Hyperloop超級高鐵項目距離成為現實又近了一步。

????這位特斯拉汽車公司創始人在上周四表示，他打算為這一極速交通系統建造測試設施。穆斯克在一條推文中稱，測試用的5英里長軌道最有可能建在德克薩斯州。

????穆斯克的Hyperloop可以將乘客用安全帶固定在乘坐艙中，并通過特制的管道以驚人的速度將他們送至目的地。理論上，從舊金山到洛杉磯500英里（約合800公里）的路程只需要不到半小時。

????穆斯克目前持有的產業包括包含豪華汽車公司特斯拉、私人太空飛行公司Space X和太陽能服務公司SolarCity。他在18個月前首次提出了Hyperloop的大膽設想。從那以后，他一直專注于日常工作，很少提及這個話題。

????但在周四的德克薩斯交通論壇上，穆斯克舊話重提，隨后還發布了一系列推文。在一條推文中，他表示Hyperloop軌道將對其他公司和學生開放，“邀請他們測試乘坐艙。”他還考慮在學生當中舉辦年度“乘坐艙競速”比賽。穆斯克并未提及這一軌道是否只作為開放的測試場地，以及他是否還會在那里試驗自己的新想法。

????除了討論Hyperloop，穆斯克還表示他已經向生命未來研究所捐贈了1000萬美元，保證人工智能可以“造福人類”。他擔心機器人有一天可能足夠智能和獨立，從而反抗人類，就像科幻小說中描繪的那樣。

????在這家機構網站上的一段視頻中，穆斯克表示：“與其等著這種糟糕的情況發生，然后再設法應對，不如現在就做好措施，阻止它出現。”（財富中文網）

????Elon Musk just brought his Hyperloop project one step closer to reality.

????The Tesla Motors founder said Thursday he intends to build a testing facility for the ultra-fast transportation system. The five-mile track would most likely be in Texas, Musk said in a tweet.

????Musk’s Hyperloop would involve strapping passengers into pods, or a train, and shooting them through a tube at warp-speed to their destination. In theory, a 500-mile trip between San Francisco and Los Angeles would take less than an hour.

????Musk, whose projects include luxury electric car company Tesla TSLA -0.43% , the private space flight company Space X, and solar power installer SolarCity SCTY -4.80% , first laid out his audacious vision for a Hyperloop 18 months ago. Since then, he’s remained mostly silent about the topic while focusing on his day jobs.

????But on Thursday Musk addressed the topic once again on stage at the Texas Transportation Forum, and then in a series of tweets. He said in a tweet that his Hyperloop track would be open to other companies and students “to test out their pods.” He also mused about holding an annual student “pod racer” competition. Musk did not mention whether his track would merely serve as an open test-bed, or whether he would also try out his own ideas there.

????In addition to discussing the Hyperloop project, Musk said he had donated $10 million to the Future of Life Institute, to ensure that artificial intelligence is “beneficial to humanity.” His concern is that robots could one day be smart and independent enough to rise up against humans, like in the plot of a pulp science fiction novel.

????“It is best to prepare for, to try to prevent a negative circumstance from occurring, than to wait for it to occur and then be reactive,” Musk said in a video posted on the institute’s website.
