Speaking on disruptive technologies - IT that creates a step-change in the way we do business - Mannings, BT's university research programme manager and the link with BT's Disruptive Lab at the Massachusetts Institute of Technology, said breakthroughs occur when a new business model rides on a new technology.
"It was the change in the business model to pre-paid mobile phones that brought about widespread texting," he said.
"We should look to younger people for innovative ways of exploiting wireless, ubiquitous computing enabled through low-power wireless peer-to-peer applications and novel uses of RFID.
"Although RFID tagging is used in commercial applications such as supply chain management, if a 'physical cookie' was embedded in RFID tags in clothing, it could be used for lifestyle applications. For example, people would be able to meet their partners via RFID tags."
Mannings' vision for the future included developments in ad hoc non-centralised networks, peer-to-peer business applications, edge-of-network intelligence, grid computing, open source hardware and software, information storage at one bit per 20 atoms, semantic encoding, ubiquitous computing and low-power wireless.
With such a raft of technology and easily accessible applications, the real profit for the future will be in the command and control of the IT infrastructure.
