Boxabl Folding House - What do you think?

I was watching a video about these new folding houses and was amazed.  I think they are still in the development stages, but I could see this being incredible to set up a new AirBnb or even a mother-in-law home on your property.  I'm curious what you guys think about this.  I saw a price for $15,000 but I'm not sure if that's for a certain style.  I also saw some that were fully solar and that was what really interested me.  I'm still researching this, but considering adding something like this to my homestead when they come out.  

If you're interested in researching this as well here's the link https://fas.st/t/ciH8892S
