We must understand that we are in a massive competition to who has the best system and that means propaganda. That is a huge problem of building in a neoliberal fashion as it cuts any sort of beauty for cost purposes. That is wrong as beauty is not only improving the actual building or thing, but also makes it last longer as we lack the desire to destroy it for something better. In my opinion there is one project necessary, which has to create a lot of new great construction in a solarpunk world, which is beautiful. That is the massive improvment to public transport. We need some massive new central stations in cities and it would be muc better to build them in a solarpunk style then anything else. Same is true for large scale improvements of current stations. They need to be made more beautiful.
