Not trying to say it's inevitable but it's way riskier. There's usually a company behind that selling the software making money to continue the process. Bret has a non-profit and now no physical location to evangelize from. Libraries are an exact counter example to this actually, first the idea doesn't require software and hardware, and second the concept is all there really is to it. Making a DynamicLand clone is clearly possible without access to the code but you have to do a lot of blind reverse engineering working backwards from the implementation.
Maybe this is also a little frustration that it's been 10 or so years and there's not actually much new news, it looks better but I'm seemingly further than ever from being able to experiment with it.
