    A research has shown that nearly 90 percent of traffic accidents are caused by human errors. So our aim is a fully autonomous car that gets rid of the cause of most accidents: the driver. Researcher Hodgson points out, “For safety, the faster you can remove humans, the better, even if there are unfortunately a few accidents from new causes. It s a question of balancing the number injured or killed by autonomous vehicles with the people whose lives are potentially saved.”

    It’s an idea that Elon Musk, chief executive of electric car company Tesla Motors, has long believed. His company are determined to be the first to deliver a fully autonomous vehicle to consumers. Last year, Musk announced that Tesla’s 2017 goal was “to do an example drive of full autonomy all the way from LA to New York…and have the car park itself.”

    However, even Tesla admits that there are problems to overcome—the software needs further validation and the appropriate regulatory approval needs to be in place. Indeed, recent crashes of Tesla vehicles and Google cars confirm that the software isn’t ready yet.

    The UK government appears committed to encouraging the development of autonomous vehicles. It’s supporting four city trials, publishing the Modem Transport Bill to reduce red tape around their introduction and adapting the legal system to take into account problems such as insurance liability when a human isn’t in control of a vehicle.

    The insurance industry is similarly eager to help increase autonomy in cars. As the Association of British Insurers (ABI) points out, “More than 90 per cent of road accidents are caused by human error.” This costs motor insurers a shocking £20m per day in claims.

喧嚣时代,诗歌何为?

陈劲松

       ①在21世纪的今天,诗歌作为一种特殊的文学载体,或许随着时代的发展、文学的发展以及审美取向的变化,逐渐面临边缘化的境遇。一方面是追求诗歌精神的终极关怀,另一方面则是越来越喧嚣的世俗诱惑;一方面是回归古典的儒雅情怀、物我两忘的传统气度,另一方面则是写诗者多于读诗者的残酷现实。诗歌就在这种两难境地进退维谷。然而,诗歌在当下的文学视野中真的就渐行渐远,在日益高涨的城市化进程中真的就不堪一击了么?

       ②不必讳言,当下诗歌的确存在一些问题。诗人圈子化、作品浅俗化,即是例证。过分的炒作与包装、不时爆出的抄袭丑闻、哗众取宠的行文艺术,诸如此类,让本应圣洁的诗坛一片乌烟瘴气,而诗歌,这原本富有生命的艺术载体,也随之变得苍白无力而又缺乏灵气。由此造成的后果之一是,当下文学存在一个引人深思的诗歌误区:将诗歌陌生化、边缘化;将诗人妖魔化、另类化。

       ③对此,我的看法是,人间自有好诗在,对于诗歌的当下和未来,虽不能盲目乐观,也不必过于悲观。就中国当代诗歌来说,自20世纪70年代末80年代初发展至今,已经有30多年的历程。尽管每一个时期的精神氛围和物质载体有着明显区别,但诗人们的写作取得了瞩目成就,却是勿庸置疑的事实,在几代诗人的努力下,中国当代诗歌逐渐臻于成熟和完善。

       ④透过被时代喧嚣遮蔽的诗歌景象,我们看到:真正的诗歌应该是也必然是生命的宣言、生活的自白,诗意地阐释着人类生命,诗化地阐释着真实生活;真正的诗人应该是也必然是人类精神家园的守望者,清醒地守望着整个世界,守望着全部人类。诗歌之为诗歌,是因为它“从生活出发,从心灵出发,直抵人世间的那种渺小、虚无、道德、悲悯和感伤。”1985年,诗人罗伯特•佩恩•沃伦被美国国会图书馆授予“桂冠诗人”称号之后,他在与《美国新闻与世界报道》杂志记者的访谈中说了一句话:“诗歌就是生活。”我对此的理解是:因为生活里有一种巨大无比的潜在力量,给诗歌带来一种无法妥协的勇气与激情。使得在诗人眼里,诗歌就是我们周围的一切,就是我们的心灵和大地,就是自然界的万事万物。

       ⑤德国诗人荷尔德林曾说:“人诗意地,栖居在这片大地之上”。既然“诗歌就是生活”,那么就让我们的诗人们,在这个喧嚣时代的生活中去发现诗意,寻觅诗情,写出一首自己生命的大诗,进而保持诗人应有的尊严、复活诗歌曾经的荣光吧!
