What the milestones involve or at least have it bookmarked to check. Also stop reading line by line the NR's and trying to break them down without any context. PC already talks about the prototype and much more in a past "recent" NR being completed by around the end of the year. This is the prototype and third party validation they are talking about. They've achieved it on their scale now need to make sure it can be mass produced/completed in a fab. As we've done in the past and will continue to do. Read the NR's with the understanding of the previous NR's. Doesn't help we have people on here that are looked up to for whatever reason and just highlight specific words out of full NR's with no context and completely misunderstand what is being said. There's a select few on here that know what they are talking about. I'd suggest listening to them. Start with Rob and oogee as a starting point then go from there.
