Predicting the future 預(yù)測(cè)未來(lái)

Predicting the future is notoriously difficult. Who could have imagined, in the mid 1970s, for example, that by the end of the 20th century, computers would be as common in people's homes as TV sets? In the 1970s, computers were common enough, but only in big business, government departments, and large organizations. These were the so-called mainframe machines. Mainframe computers were very large indeed, often occupying whole air-conditioned rooms, employing full-time technicians and run on specially-written software. Though these large machines still exist, many of their functions have been taken over by small powerful personal computers, commonly known as PCs.

眾所周知，預(yù)測(cè)未來(lái)是非常困難的。舉個(gè)例子吧，在20世紀(jì)70年代中葉又有誰(shuí)能想得到在20世紀(jì)末的時(shí)候，家庭用的計(jì)算機(jī)會(huì)像電視機(jī)一樣普遍?在70年代，計(jì)算機(jī)已經(jīng)相當(dāng)普及了，但只用在大公司，政府部門(mén)和大的組織之中，它們被稱為主機(jī)。計(jì)算機(jī)主機(jī)確實(shí)很大，常常占據(jù)了裝有空調(diào)的多間房間，雇用專(zhuān)職的技師，而且得用專(zhuān)門(mén)編寫(xiě)的軟件才能運(yùn)行。雖然這種大計(jì)算機(jī)仍然存在，但它們的許多功能已被體積小但功能齊全的個(gè)人電腦——即我們常說(shuō)的PC機(jī)——所代替了。
