Some people in this thread need to attend to the dev diaries. Specifically, they need to read
Wiz 6:1, which says:
So, you still have the key elements of the AI Crisis as it was originally envisioned are there: robot uprisings popping up throughout the galaxy, of threats from within and without. What it adds is this new concept of the Contingency, which makes sense of the elements that were already in the crisis but didn't actually fit the lore of the original - the AI Homeworld that just appears.
The reason the old AI crisis fundamentally didn't work (aside from all the bugs - most of the time it just sat around and did nothing, didn't purge organic pops, purged the wrong pops etc - it was a clusterfuck) is that it's supposed to start from isolated uprising and glow into a galactic threat on the strength of the bonuses that machine pops and their government type gave them. Against late game empires, that was never going to happen. I don't care how good your research buffs are. That's why it's now been given this big ass fleet to start with.
