- edge of punctuated equilibrium: we reach a Kardashev level and getting through it requires major breakthrough again - would produce a flattening increasing sigmoid zigzag
- slow catastrophe pending resource depletion outstripping rate of innovation or travel, very slowly reversing progress
- singularity immediately halting the progress - flat horizontal line - the Accelerando situation
- potential speciation or technological fragmentation where it stops to be useful to talk about a single progress
