摘要

In the VLBI2010 session we are trying to predict the world a mere seven years in the future. In these seven years the infrastructure in computing and data communications will change more than anybody realizes now. We can get some insight about the rate of change by looking back seven years into year 1996. At that time microcomputers had 133MHz processors, 16MB of main memory and the largest hard disk was 2GB. Mainstream networking technology was 10Mbit/s Ethernet, the first 100Mbit/s equipment was starting to arrive. Global Internet connections were typically 155Mbit/s at their best. Now we have 3GHz processors (22 times improvement), 1GB main memory (62 times more), 200GB hard disks (100 times larger) and 1Gbit/s Ethernet networking (100 times faster). Internet backbone networks routinely use 10Gbit/s connections (66 times faster). If the trend continues, in 2010 we will have 66GHz processors with 60GB main memory and 20TB hard disks. Networks will work at 100Gbit/s speeds. Global connectivity will be available at 660Gbit/s. Of course these numbers are wrong in details, but it is better to use them than to think in terms of today's technology. It is imperative that we do our development work as fast as the computer industry and we must accept that at least one generation (possibly two) of VLBI equipment will become totally obsolete before we reach 2010.
