Let's be clear fpr a moment.
If you play this game x hours a day every day, then you can achieve a lot (perhaps you have ships outfitted tand modded for large distance jumps to get to the engineers or already have a decent vehicle stored for x purpose etc.) this all results in having more time available for the other aspects such as encountering and interacting ro discovering the 'new exciting things'.
Also, let's go back about 10 months. Some people were getting multiply hyperdicted, wherwas others never encountered a Thargoid at all until post 2.4 despite mostly 'living' around the Pleides and doing everything they could to them off...
You need to bear in mind an aspect of SCALE. This game has a few players, not just you. and of thiose players, many are perfectly vested and pay much into the merchandise, but simply don't actually have the same amount of in-game active playtime. Which further means, they may require to maximise their limted time, for example, if they only have 5 hours to play in a given week, then it is some proportion of those 5 hours that must be spent on the CG should they seek top participate. For someone who has 10 hours to play over that same week, they can spend 5 hours on anything, and still make some proportion of those 5 hours hauling for the CG - jsut an example that not all playtime is equivalent when the game features timelimited features.
So when it comes to the development of a narrative story, even something that in "reality" woudlö develop rapidly maybe even within one day (even in our current time, with global telecommunications and media provision over the internet, you can watch things like Don Trump'sAsian visit unfold and gain updates even hourly or better throughout the day --- HOWEVER, ED is INTERACTIVE. FDev want to give the most players an opportunity to be aware of developments, act upon or interact with something related to the developments, and have the chance to be a part of things before they move on to the next aspect.
Given the entire Thargoid development has been from fairly rare cutscene hyperdiction to actual combat, hundreds of NHSS in populated space, arms race and weapon tech development in 4 weeks, this is really very fast.
