Our daily existence is divided into two phases, as distinct as day and night. We call them work and play. We work many hours a day and we allow the necessary minimum for such activities as eating and shopping. 46) The rest we spend in various activities which are known as recreations, an elegant word which disguises the fact that we usually do not even play in our hours of leisure, but spend them in various forms of passive enjoyment or entertainment.We need to make, therefore, a hard-and-fast distinction not only between work and play but, equally, between active play and passive entertainment. 47) It is, I suppose, the decline of active play — of amateur sport — and the enormous growth of purely receptive entertainment which have given rise to a sociological interest in the problem. If the greater part of the population, instead of indulging in sport, spend their hours of leisure "viewing" television programs, there will inevitably be a decline in health and physique. In addition, we have yet to trace the mental and moral consequences of prolonged diet of sentimental or sensational spectacles on the screen. 48) There is, if we are optimistic, the possibility that the diet is too thin and unnourishing to have much permanent effect on anybody. Nine films out of ten seem to leave absolutely no impression on the mind or imagination of those who have seen them.49) It is only when entertainment is active, participated in, practiced, that it can properly be called play, and as such it is a natural use of leisure. In that sense play stands in contrast to work, and is usually regarded as an activity that alternates with work.Work itself is not a single concept. We say quite generally that we work in order to make a living. Some of us work physically, tilling the land, minding the machines, digging the coal; others work mentally, keeping accounts, inventing machines, teaching and preaching, managing and governing. 50) There does not seem to be any factor common to all these diverse occupations, except that they consume our time, and leave us little leisure. 46) The rest we spend in various activities which are known as recreations, an elegant word which disguises the fact that we usually do not even play in our hours of leisure, but spend them in various forms of passive enjoyment or entertainment.

In November the European Parliament’s culture and education committee is due to move forward on its proposed "audiovisual media services" directive, before sending it to the full parliament in December. The new rules update and relax the "Television Without Frontiers" directive of 1989, which opened Europe’s national markets. But critics complain that they also seek to extend fusty regulations from the era of broadcast television to today’s very different technologies. Rules on advertising, the protection of children and so on could potentially also apply to all kinds of video streams, including video blogs, online games and mobile-video services.This could have a chilling effect on innovation and risks stifling emerging technologies with rules designed for another age, says Chris Marsden of RAND Europe, a think-tank that has analysed the potential impact of the proposed rules for Ofcom, Britain’s media and telecoms regulator. "Regulators have to be thoughtful. They cannot predict the future of television "or the internet—no one can," says Niklas Zennstr. m, a co-founder of Skype, who is now setting up an internet television firm.The proposed rules may be unrealistic as well as onerous. The idea that websites can be regulated like broadcasters, which are required to keep strict records of what they show in order to help watchdogs investigate complaints, is untenable. Firms could simply relocate outside the European Union to escape the new rules. Last week Ruth Hieronymi, a member of parliament, said she would introduce wording that might help to overcome some of the objections.Behind the debate is the question of how best to balance competition and protection. Traditional broadcasters worry that they will be shackled by regulations while brisk start-ups can do as they please—so they like the idea of extending regulation to their new rivals. But even if the rules are approved as they stand, they will not come into force until 2010. Such a long, slow process seems incongruous given the pace of technological change. Why Traditional broadcasters want to extend regulations to the new broadcasters()
A. Because they are chained by regulations while the new rivals are free from them
Because it is hard to balance competition and protection
C. Because the new broadcasters are more adapted to the regulations
D. Because the rules come into force in a slow and long process
Will humans always be superior to machinesThis statement actually consists of a series of three related claims: (1) machines are tools of human minds; (2) human minds will always be superior to machines; and (3) it is because machines are human ’tools that human minds will always be superior to machines. While I concede the first claim, whether I agree with the other two claims depends partly on how one defines "superiority," and partly on how willing one is to humble oneself to the unknown future scenarios.(41) After all, would any machine even exist unless a human being invented it Of course not. Moreover, I would be hard-pressed to think of any machine that cannot be described as a tool. Even machines designed to entertain or amuse us—for example, toy robots, cars and video games, and novelty items—are in fact tools, which their inventors and promoters use for engaging in commerce and the business of entertainment and amusement.(42) And, the claim that a machine can be an end in itself, without purpose or utilitarian function for humans whatsoever, is dubious at best, since I cannot conjure up even a single example of any such machine.(43) As for the statement’s second claim, in certain respects machines are superior. We have devised machines that perform number-crunching and other rote cerebral tasks with greater accuracy and speed than human minds ever could. However, if one defines superiority not in terms of competence in performing rote tasks but rather in other ways, human minds are superior. Machines have no capacity for independent thought, for making judgments based on normative considerations, or for developing emotional responses to intellectual problems.(44)Up until now, the notion of human-made machines that develop the ability to think on their own, and to develop so-called "emotional intelligence," has been pure fiction. Besides, even in fiction we humans ultimately prevail over such machines—as in the cases of Frankenstein’s monster and Hat, the computer in 2001: A Space Odyssey. Yet it seems presumptuous to assert with confidence that humans will always maintain their superior status over their machines. In other words, machines will soon exhibit the traits to which we humans attribute our own superiority.(45) And insofar as humans have the unique capacity for independent thought, subjective judgment, and emotional response, it also seems fair to claim superiority over our machines. Besides, should we ever become so clever a species as to devise machines that can truly think for themselves and look out for their own well-being, then query whether these machines of the future would be "machines" anymore.[A] Recent advances in biotechnology, particularly in the area of human genome research, suggest that within the twenty-first century we’ll witness machines that can learn to think on their own, to repair and nurture themselves, to experience Visceral sensations, and so forth.[B] The statement is clearly accurate insofar as machines are tools of human minds.[C] In sum, because we devise machines in order that they may serve us, it is fair to characterize machines as "tools of human minds."[D] It’s hardly surprising that human-made machine can do the most works that belong to human before.[E] In fact, it is because we can devise machines that are superior in these respects that we devise them--as our tools—to begin with.[F] When we develop any sort of machine we always have some sort of end in mind—a purpose for that machine. 43()
