*             30000 baud gets us to ~28.8k
*            300000 baud was about 2 ISDN lines (2x128k)

Well using your logic, then it's partially true that 40G is not any time soon. Especially considering fiber is in less than 1% of homes. Lets not forget that all of the above has been established on existing facilities that have been in homes for 30-50+ years.

You say 30 years ago, and lets roughly estimate it's four to five years between those technologies above, which gets us to today. It's going to take at least another 5 years to consider FTTP "the norm" at say 30M, maybe sooner with technologies with DOCSIS 2.0, etc. So...

30M    Is Today +4/5 years
300M   Is Today +8/10 years
3G     Is Today +12/15 years
30G    Is Today +16/20 years

If it's sooner all the better. Keeping in mind, installations like Verizon FiOS don't run dedicated strands of glass to each home, they use PON. So achieving anywhere near 40G on even the existing stuff they're running into homes may not be possible for quite some time...

PS -- baud != bps
