I read Stewart's message differently. If I understood it correctly, it was about thinking about the long-term evolution of the Internet. A person can look at the details (what is referred to as "in the small") if he/she has the time to do that. The person might still have to look at the broad picture if he/she is interested in the evolutionary/architectural aspects. >Most of the problems the long history of IP >replacements (including the ones I've worked on, >and continue to work on) over the years have >identified aren't really technical, or at least >are not technical in tractably addressable ways >(the speed of light and the fact that all >operations one can do in a network have strictly >nonnegative latency are problems as old and hard >as the non existence of perpetual motion >machines).

Some points (please see above) could be doable without replacing IAB members with economists. There is a message from the IAB at https://mailarchive.ietf.org/arch/msg/ietf/AWEWI7rCmbOzifT5xQRpyciPLE8/ It is understandable that it has to see to the other aspects of its Charter. I could not find anything [1] in there which takes a "let's think ahead" approach or a "let's rethink". The recent events could produce a significant shift in the existing models. Regards, S. Moonesamy 1. There may be an exception to that. It may take a few years to see whether that is actually the case.
