We've yet to be able to replicate it from the old parts of meat we know are involved in it with the addition of electricity in the ways it should need in even the much simpler flesh of insects, amphibians, and reptiles. Best we can do is make a muscle twitch without causing observable thought/emergent nureaul processes.
So even if we can, we're so far from it that thinking we're on the cusp seems delusional to me.
Edit: as response shows, we have in fact also gotten it brain cell "twitches" by direct stimulation of braincells. Sadly it didn't seem to be rigged up to measure overall brain activity.
