News reports and official accounts show that the Ever Given ran aground in the Suez Canal on 23 March 2021 and was freed on 29 March 2021, meaning it remained stuck for about six days, not an additional 1–2 weeks from the date of the podcast on 27 March 2021. (en.wikipedia.org)

Multiple sources report that the ship was fully refloated and free to move in the canal on 29 March 2021 at about 15:05 local time, after intensive dredging of sand and mud around the bow and coordinated tugboat operations over several days. (theguardian.com)

Friedberg’s mechanism expectation (digging around the sand plus tugboats) matches what actually happened: dredgers removed tens of thousands of cubic meters of sand and mud while a flotilla of tugboats pushed and pulled the ship free. (theguardian.com)

However, his timing prediction — that it would take "another week or two" from late March 2021 — was clearly off, because the ship was freed roughly two days after the conversation date, not 7–14 days. Since the prediction included a specific time frame that did not occur, the prediction as stated is best judged wrong, even though the described method was broadly accurate.
