New technology comes at a price. The have spent billions on R&D and this is a way to get some of the investment monetized. It is likely to be a niche product to test the technology and the market. Most likely in a couple of years we will have foldable screen phones that go for less than $1000
There are no termites in colder climates. The material can be coated to precent any insect from eating it. If you think avout what happened in New York 15 years ago today one might argue steel and concrete burn just as well as wood
While the US is likely the largest market, there are plenty of opportunities elsewhere. Ignoring those might be part of your strategy, however if you are willing to take look at what Europe or Asia have to offer you might be facing something quite unexpected as there are tech start-ups everywhere.

If your plan is to create a thriving project that aims to address a specific business problem, you are going to need a group (even small) of likely minded people.

Why exactly do you want to be in the US? I've lived in Moscow and St. Petersburg for quite some time. It is hard to imagine, that you won't find anyone in those cities with summed population of almost 20 million, who is willing to work with you on your or their ideas.
This looks absolutely stunning. I wish I could train the brain by myself and see how it operates in as an artificial neural network. Anyway, great job!
