Well that's one place we can agree anyway, trial and error are very valuable tools, they just need to be weilded carefully and not considered an error too soon. That makes it risky though.

I know i come of as pessimistic, and by a lot of measures i am, but usually only in comparison to the dismissive or condescending attitudes many people seem to have on the subject. Just build trains, duh... They work here, just do it there!

The backlash to poorly thought it arguments are usually people doubling down on their argument in the other direction, so I'd prefer to temper optimism and encourage actual conversation. Even if i may have trouble with that second part :)
