It seems like 2030's will be quite different decade compared to 00's/20's, if we have to assume that "singularity" is reached around 2028-2030.

But I'm betting that 2030's will be more of a transitional decade as humanity attempts to integrate the quick advancements of "singularity" into functions of society. How long it'll take, remains a question to be seen.

Then by 2040's, we'll be more than likely to see it as a completely different decade from 00's/20's, maybe unrecognizable at best.
