Tapestry
In a solo game, do tech card prerequisites have to be met by a neighbour, or can you meet them yourself?
The rulebook lets you or a neighbour meet the requirement, and a solo game has no neighbour to use.

You can meet a prerequisite yourself, as well as through a neighbour. In a solo game there are no neighbouring players to rely on, so you must meet the requirement with your own tier, income or buildings.
