now that is emotive bull***.  not only do you have no clue about the
nature of metals and metal joining, you're throwing about words you
don't really understand.  

It's _you_ who don't really understand this stuff, because you just
looked up some data in a table, came to some uninformed conclusions
about the implications thereof, and decided everybody else is wrong.
I have made, actually made, real machines and components out of most
of the materials you presume to know so much about. I have done
things with them that no table or graph could contain. And I have
done these things in some of the most ambitious research and
development settings the private sector has to offer. Bikes are the
least of it-- they are what I make when I want to play and take it
easy. So when I use non-engineering terms like "forgiving", "sloppy",
"unreliable", or "consistent", it's based upon direct, hands-on
observation and successful or sometimes failed attempts to get these
materials to do what they are purported to do.

You? You are just full of crap and hot gas. I'd wager you have never
worked with these materials more than to bodge them up with
sandpaper. Have you ever even cut one original thread? Have you ever
even brazed one single fillet? The way you talk about this stuff, you
definitely do not come across as someone who has done any of these
things. You have a lot to say about metals' internal microstructure
like it was something you personally discovered, but have you ever
been responsible for changing a metal item's microstructure? No, you
haven't.

So you go make a bike frame out of carbon band-aids and synthetic
boogers and ride it a while, and report back. If you haven't been
totally demoralized by the experience and you have any inclination to
make another frame, it will be made of metal, guaranteed.
