All the electronics of the Liberty Phone are made in our USA facility, and the entire phone is assembled at that same facility.

I suppose that this is the reason for the high price. It’s built all in one single factory in the US (I was too lazy to research if it’s their factory). I hope that their target groups are real and that they can afford the phone.

Also communication: issues, blockers, requirements, expectations. Nothing works without these things and the ones you mentioned.

Critical thinking is definitely important, but I would say that the most underrated skill is communication (spoken and written).
