  • No-one will ever use 100 Mb/s to the home
  • Wireless can provide 100 Mb/s to the home
  • Future advances in wireless will make FTTP obsolete
  • Advanced DSL will provide 100 Mb/s to the home
  • FTTH is environmentally unfriendly
  • Australia is taking a risk in going to FTTP before the rest of the world

"The Americans have need of the telephone, but we do not. We have plenty of messenger boys.“

  • - Sir William Preece, chief engineer of the British Post Office, 1876

"I think there is a world market for maybe five computers."

  • - Thomas Watson, Chairman of IBM, 1943

"There is no reason anyone would want a computer in their home."

  • - Ken Olson, president and founder of Digital Equipment Corp., 1977

"But what...is it good for?“

  • - Engineer at the Advanced Computing Systems Division of IBM, 1968,

commenting on the microchip
