I'm not saying it's easy........I'm going directly off of what Tesla said on the earnings call about the progress of the 4680 Cells and specifically the dry electrode process.
Someone actually replied to that tweet already with direct quotes from the Q4 earnings call. When the Tesla team is saying "Meanwhile, we've developed enough engineering confidence with our 4680 design and the production process and equipment to kick off manufacturing equipment and facility construction to support our 100 gigawatt hour 2022 goal"........then inclined to believe them over some random person on Twitter saying there's a rumor and then using very outdated quotes to back up their rumor.
