For purposes of the show and universe It’s the same Picard. Just like Spock in movies 3-6, and tng is still referred to as Spock not some regenerated entity that had its memories placed into it. Technically the memories of of the original Spock died in wrath of khan

Not sure how factually stating 3 of the 5 shows are not completely serialized has anything to do with pettiness. I said there have been 11 seasons of trek. That person responded by saying they have been depressing serialized drama which is not accurate.
