What makes you think kernel developers have a deep understanding of the 
value of connectivity in the OS? They don't. The average kernel 
developer is not particularly bright. Just ask Ted why htrees are slower 
than reiser4, or ext2 tail combining is slower, and, well, he has no 
clue. He is happy to explain how architects don't do real work and 
should not attend the Linux Kernel Summit, and then when reiser4 blows 
htrees away he undoubtedly still thinks I just take the credit away from 
the programmers who do the real work. They did real work, and they are 
the best in the field, but architecture also matters --- quite a lot 
actually.

Maybe instead of free trade, I should have used anti-trust laws as my 
example. The percentage of persons who analytically understand both that 
free trade is vital and that anti-trust laws are a good thing is very 
small (and especially small at Harvard Law School). Average people can 
understand freedom. Understanding that one is not really free to choose 
to not purchase from a cartel is hard for many. Understanding that free 
markets are only a first approximation and that is why we need 
anti-trust laws is beyond perhaps even most economics PhDs.

This is not due to a lack of education. I once had a boss explain to me 
how many people have trouble understanding orders of magnitude and 
ratios. He particularly meant his boss, who was having trouble 
understanding my report.

We all have mental defects, we just have them in different areas from 
each other. (Forgive me for not enumerating mine....;-) ) Some technical 
matters are understood by much less than 50% of the population. Closure 
is one of them. For most people the value of closure can only be 
understood by using and liking a system that has it, and they are not 
capable of wanting it in advance during the design stages. Codd 
understood the importance of closure. You could sense his frustration at 
being unable to convey it to others in his writings. The search engine 
industry completely misses the importance of closure.

This is why I just want to be left alone to tinker with reiser4. It is 
faster than other filesystems. People should assume I know what I am 
doing, and leave me to tinker in my little fs. 5 years later others will 
follow, or not, I don't care.

Yes, I did. Got no response. Would you like me to post something nice 
and technical to this thread?;-) I can send a summary of my design, and 
the answers I sent to Viro and Linus.
