NO. The AI does cheat. In fact, hard AI's get a 50% economic advantage.
Here is a basic starting setup if you'd like to try it... this works for me more often than not (so far, hasn't failed me yet) for TEC.1 Right away, and I mean immediately buy 100 units of crystal, and no more.2 Upgrade your home world population infrastructure one level.3 Build your cap ship factory, highly recommend a cap ship with colonize if it's not too small a map.4 Build your mineral/crystal extractors while this is going on, and queue up two scouts. Put those on auto explore.Do these four+ things right away, then let the info you learn from the scouts determine your next move.This should use up the majority of resources you started with. From here things get pretty situational. A hard and fast build list means you're probably not paying attention nor reacting to immediate events, which I consider crucial to survive the initial stages of the game until you've established an economy and some defence choke points. The map layout is key here. If there are lots of ice/volcanic worlds around, I throw up two civ stations, get the appropriate planet tech first and then go trade centers. Otherwise I put up 1 or 2 military centers and go for LRMs (I'm still working on TEC). Either way I start filling out my fleet ASAP.I'm finding especially early game, military upgrades aren't worth it while making sure you're using as much of your fleet capacity as possible is very important. You're paying upkeep irregardless if it's full strength or not so I recommend keeping it maxed, plus try not to upgrade your logistics until you really have to.I'm writing a strategy guide for newer players and will go more into detail then... hope this is helpful. The first handful of minutes in the game are pretty far reaching in consequence.
Good ideas. But they will not help you against a hard AI as TEC.
Here's what you have to know as TEC to win against a hard AI:
The AI always builds a lot of light frigates at the start, but it cannot really seige your base with them. The exception is Vasari. It tries to seige your base with the frigate.
DO NOT build these yourself. Light frigates counter seige frigates (useless when you don't have anything to hold the front), and they counter support craft. Your opponent doesn't even have those... He has more light frigates. A human advent player will sometimes churn out support craft early on, but that's another story. (It kills the LRM rush if he does it right)
My suggestion is that you immediately tech to LRM's, and focus on extracting crystal. Do not buy it in the beginning unless you have no other way to get it. Put some metal on the market and hope someone buys it, if you resort to buying crystal.
I play Advent mostly, but I hope this helps.
