This is the most useful comment in the thread (so far)!
This product would not work at all for any analog or power designs--EEs like to visualize current flow and a schematic is the best way to do that. Maybe if it could interoperate with small blocks of schematics, treating them as modules, it could be useful. If there was a way to parameterize part values, like those used to build analog filters, that could also be useful, but not in the current text-only form.
The one thing it could be useful for is creating net connectivity for large numbers of pin to pin connections, like DDR memory or PCIe buses. Schematics for these end up looking like large data tables anyway, and can be tedious to create and prone to errors.
I see so many EDA startups using their product for simple Arduino boards and other low to medium complexity designs. It's far more effective to start with the most complex board design. Take a server board from the OpenCompute project with a few thousands parts and a few tens of thousands of nets. What would that look like in this language? Would it have too much boilerplate code? What would the experience of creating it be like? How do you handle back annotation? How do you handle pin swaps, or part section swaps? How about BOM variants?
