1.In part, the sudden re-emergence of technological progress is the climax of years of research in different fields that are finally reaching critical mass.2.The Internet only became a commercial proposition in the mid-1990s. 3.The first successful gene-splicing (基因拼接) experiment was done in 1973, but biotechnology is only now set to explode.4.Moreover, different parts of the innovation wave are starting to feed reinforce one another, as fast computers greatly accelerate the ability of scientists to understmanipulate genes. 5.On the contrary, biological techniques now seem the best foundations for developing tomorrow's new generation computers.
