It seems to me like Brad, etc al. is hearing what we are saying, but not understanding (or understanding, but unable to do it). Many people have been asking for a smarter AI. The computer does some really dumb things in some places. The thing is, most people didn't envision nerfing trade goods as the fix for a smarter AI.
What I (possibly we) have been requesting since the beginning is better map management by the AI. Better use/defense of star bases. Better tactical manuevering during battles. More intelligent choices when deciding to go to war. Somehow this got translated intoto ('the game is too easy, let's nerf something').
On the higher levels trade goods are (were) a really good way of leveling the playing field with the AI. The AI is generally better at managing it's economy, morale, tech, etc. than a human. My feeling is this is because this is a closed equation (there is a 'best' way to do it). The AI is not very good at the open equations (no 'best' solution.. or if there is one, it's really complex) like how to strategically place ships for a tactical win.
Not that this is any suprise, people have been working on making AI think like people for 60 years and still haven't figured it out. However, IMHO, I'd much prefer incremental upgrades to the 'hard' AI problems, than arbitrarily making the game more difficult for me to win by nerfing something that levels the early game.
We're not looking for an impossible to win game. We're looking for a single player experience that plays like you are challenging another human player. Hehe.. I can see the headlines a year from now, 'Galactic Civilizations passes the Turing Test'.
