Watch how drones have been presented on the TED stage in various ways over 15 years.
1998年，飞行器设计师保罗·麦克里迪在蒙特雷的TED舞台上对他那架重仅两盎司的无人侦察机进行了现场演示。”你能看到它所看到的一切。想象你是一只苍蝇，”他对台下的观众说道，观众们注视着无人机拍摄的画面投影在眼前的屏幕上。（这一瞬间被定格在下方的GIF图中。）令全场为之振奋的是，无人机在头顶呼啸而过，绕着礼堂盘旋，实时回传视频画面。
“这一切将通向何方，我不得而知，”麦克里迪坦言，”它是否实用？我也不确定。”
此后15年的发展已经给出了全面而明确的答案。无人机不仅切实可行，更已成为生活中不可或缺的存在。它们早已今非昔比，远远超越了麦克里迪当年那架简陋的黑白摄影原型机……而更多的无人机也在TED舞台上迎来了各自的高光时刻。2012年，时任DARPA局长的雷吉娜·杜根展示了一款外形酷似普通蜂鸟的无人机。同年，维贾伊·库马尔深入阐述了”自主敏捷空中机器人”的广阔前景，并就无人机在灾难救援中的潜在作用发出了热情有力的呼吁。
