Predicting the Future Long term Vision 10 Year Vision of Telecommunications ETRI s R&D Strategy 6
Predicting the future Today s success is only 15(7) months from failure Extrapolation and Wrong predictions Recency bias Every American women will be a telephone operator Everyone will be a programmer 640K memory will be enough 300bps will be enough for data communication 7
Is it possible to predict the future? Fortune teller Stock market 8
Long Term Vision Ubiquitous Network Ubiquitous Computing Increased bandwidth between humans and machines 9
The trouble with technology visions Popular technology visions often overestimate nearterm prospects... But they underestimate long-term developments. Impact of technology Time 10
Technology costs less, content costs more Although the costs of digital-media technologies are falling, the cost of programming and the talent that creates it is rising even faster. Cost Cost of media production Bandwidth Data storage Data processing Time 11
