no you misunderstood me knux, i was talking about the fact that if you in op2 have a colony without a university, then you'll end up with a load of children. if you read the manual, or the online manual, it mentions somewhere that children are actually all untrained colonists in teh colony... so you could have an 84 year old still get counted as a child (though "children" won't have kids... ... mrrr) ... but really, you should still have workers being trained ... i mean, if you have 1 person who works at the agridome, then he could teach a child how it works ... and the same with other (non scientist) jobs.
the metal storages only need people in case there is a clog, which is dealt with by pressing a button... does that really require oxford-level training to do?
basically, all i'm saying is that, workers should still be trained in a colony, just very slowly if there is no university.
now before ppl start saying the same about the nursery, i'll point out that in op2, the two would be parents would have to go to the nursery to get screened and stuff... and to get permission, as the population has to be controlled when on an airless planet.
