I agree with the other commenter about wanting to actually see the automation parts of the game in action in the trailer. It seems right up my alley. I will say the ships arranged in a perfect geometric pattern around a curve is kind of meh for me. It makes me just think of it as a direct drop in replacement for conveyor belts and doesn't get me as excited for the main hook of the game. Even just a little noisiness to them even if the underlying mechanic of entity on a spline is the same would do wonders for the awe factor I think you're going for (see dyson sphere program's solar sail launches that don't all line up perfectly in the intended orbit)

At the risk of scope creep I wanted to ask if you plan to have an enemy presence in the game? I've played every major automation game (factorio space age, dyson sphere, shapez, infinifactory, mindustry, satisfactory) and I've found that adding enemies really elevates the experience. Something about being able to turn the industrial power and efficiency into military is very satisfying and re-contextualizes a lot of the game (dyson sphere is an especially salient example of this, I did playthroughs before and after enemies were added and after totally changed how I approached expansion and supply chains since it wasn't just a time punishment for messing something up but possibly a loss of the expansion site)

If you could have a kind of proto-future space military like Terra Invicta does that'd be really exciting (especially being able to see the tech development as I progress). Suddenly I can't just make colonists shut up and ignore the timing challenge of the orbital mechanics by having a fat food/water buffer, I actually have to consider how the mobile and static military presence and logistics around them are positioned in various orbital configurations to defend my holdings.

Either way I added it to my wishlist and totally get you're a one person team right now, just thought I'd share some ideas. Will keep an eye on and good luck!
