Predicting the future
/prɪˈdɪktɪŋ/ /ðə/ /ˈfjuːʧə/
Predicting the future is notoriously difficult. Who could have
/prɪˈdɪktɪŋ/ /ðə/ /ˈfjuːʧər/ /ɪz/ /nəʊˈtɔːrɪəsli/ /ˈdɪfɪkəlt./ /huː/ /kʊd/ /hæv/
imagined, in the mid 1970s, for example, that by the end of
/ɪˈmæʤɪnd,/ /ɪn/ /ðə/ /mɪd/ /1970ɛs,/ /fɔːr/ /ɪgˈzɑːmpl,/ /ðæt/ /baɪ/ /ði/ /ɛnd/ /ɒv/
the 20th century, computers would be as common in
/ðiː/ /20th/ /ˈsɛnʧʊri,/ /kəmˈpjuːtəz/ /wʊd/ /biː/ /æz/ /ˈkɒmən/ /ɪn/
people's homes as TV sets? In the 1970s, computers were
/ˈpiːplz/ /həʊmz/ /æz/ /ˌtiːˈviː/ /sɛts?/ /ɪn/ /ðiː/ /1970ɛs,/ /kəmˈpjuːtəz/ /wɜː/
common enough, but only in big business, government
/ˈkɒmən/ /ɪˈnʌf,/ /bʌt/ /ˈəʊnli/ /ɪn/ /bɪg/ /ˈbɪznɪs,/ /ˈgʌvnmənt/
departments, and large organizations. These were the so-
/dɪˈpɑːtmənts,/ /ænd/ /lɑːʤ/ /ˌɔːgənaɪˈzeɪʃənz./ /ðiːz/ /wɜː/ /ðə/ /səʊ-/
called main frame machines. Mainframe computers were
/kɔːld/ /ˈmeɪnfreɪm//məˈʃiːnz./ /ˈmeɪnfreɪm/ /kəmˈpjuːtəz/ /wɜː/
very large indeed, often occupying whole air-conditioned
/ˈvɛri/ /lɑːʤ/ /ɪnˈdiːd,/ /ˈɒf(ə)n/ /ˈɒkjʊpaɪɪŋ/ /həʊl/ /ˈeəkənˌdɪʃ(ə)nd/
rooms, employing full-time technicians and run on specially-
/ruːmz,/ /ɪmˈplɔɪɪŋ/ /fʊl-taɪm/ /tɛkˈnɪʃənz/ /ænd/ /rʌn/ /ɒn/ /ˈspɛʃəli-/
written software. Though these large machines still exist,
/ˈrɪtn/ /ˈsɒftweə./ /ðəʊ/ /ðiːz/ /lɑːʤ/ /məˈʃiːnz/ /stɪl/ /ɪgˈzɪst,/
many of their functions have been taken over by small
/ˈmɛni/ /ɒv/ /ðeə/ /ˈfʌŋkʃənz/ /hæv/ /biːn/ /ˈteɪkən/ /ˈəʊvə/ /baɪ/ /smɔːl/
powerful personal computers, commonly known as PCs. In

1975, aprimitive machine called the Altair, was launched in
/1975,/ /ə/ /ˈprɪmɪtɪv//məˈʃiːn/ /kɔːld/ /ði/ /ˈælteə,/ /wɒz/ /lɔːnʧt/ /ɪn/
