The problem is as soon as you implement "terminals" of any kind you very soon get a sort of "it's your everyday scifi game, just with ant visuals" feeling.
I'd rather prefer to display these "information packages" as colored dust floating through tunnels and chambers, carcasses lying around (remnants of a battle), etc. - that way ants could even look into the past, in a way that resembles the hologram scene from Prometheus.
For tech trees I HATE incremental upgrades (like armor 1, armor 2, ..., armor 10). They are stupid and most of the time useless because the enemy you face rise in strength as well, so everything stays the same and it's just wasted effort for developers and wasted time grinding for the players.
If there are upgrades they should be something MEANINGFUL. Like immunity to a certain poison, or an entirely new ability (for example a new behavior that allows ants to build bridges across smaller surface cracks with their own bodies) or upgrades that add a new trait new to an already existing unit or ability (for example the ability to freeze enemies for a short period with a sting as an upgrade to the basic "pure damage" sting or the ability for certain ant species to dig into the ground and wait there undetected for enemies to pass by).
Also powercreep needs to be avoided. Before you breed a larger or more specialized/fancy ants you should ALWAYS ask yourself "how many basic workers/soldiers can I get instead and will they be better suited to do the job" (unless of course you're in a very special special situation that definitely requires a specialist).
The Starship Troopers Tabletop does a remarkable job at this - the basic unit (the Warrior Bug) is an outstandingly good unit and unless you play a super-specialized army composition you always want them to be the backbone of your army with the specialists complementing and supporting them in various ways.
I don't want to see the game going a way were your starter ants (like the Lasius black garden ants) become utterly useless in the later levels.
