There's still Memory Beta. Our descendants might get confused given they acknowledge the show and novels, including contradictions with no attempts at reconciling them.What if something happens to Memory Alpha?! We saw what happened to it in "The Lights of Zetar"!
"Jean-Luc Picard was promoted to the rank of Admiral in 2381. In 2386 Admiral Picard retired from Starfleet and took over his family's vineyard. Then in 2387, Captain Picard faced a court-martial over his role in Section 31's forcibly removing Federation President Min Zife from office. Though Captain Picard was found innocent of criminal intent, his connection to the incident was enough to prevent him ever being promoted to Admiral. Captain Picard continued to command the Enterprise thereafter, where he continues to serve."
