There's no reason to make your theory of "civilization improvement" too complex or comprehensive. Most people would probably agree that basic repairing of infrastructure, removal of litter and trash, adding parks, etc. improves civilization. This seems relatively uncontroversial.

It is controversial, as infrastructure is not neutral and largely influences the design of cities and therefore impacts who benefits and who suffers. E.g. build streets for cars or public transportation? Build more airports or research for alternative transportation means?

Then come to a democratic solution, like literally every other problem in a democracy?

Free markets are pretty close to democracy, except instead of voting with ballots people vote with their money.

Agreed, that was my point. Which infrastructure to build and maintain, and how, can be complex questions that affect different people in different ways. Hence it is not a thing that could just be done uncontroversially.

We don't all have to agree, that's why we have democracy. We vote a government in and they make decisions about what "improve civilization means. If they get it wrong we vote new people in and they try again.

Let's see how well that works when the government actively tries to undermine the process.

As long as many people are willing to be bribed with a sliver of their future productivity brought forward to be spent today, these sorts statements usually get dismissed as being solvable within the bounds that helped enable the situation we find ourselves with today.

Moral hazards will be ignored until they no longer cannot, and not a moment sooner.

Civilization is emergent properties mainly so we must optimize society through careful education and re-persuasion and manipulation of each person. In our home economic heuristics and habitual patterns we design our life and destiny. It's a very complicated segmentation of st times parallel processes of decision making and consequential reactive reasoning. In order to facilitate higher level wisdom in our populace decision making we ought to form intelligencia amd elite in our community networks which become represented anonymously and vetted and tested according to their results. How rich, how healthy, how effective, how satisfied, and so forth. Given enough wisdom, we can make do with less resources and money. Monetary systems such as Universal Basic Income and also things like supported employment or supported entrepreneuriship and small businesses would be delivering the tools of exchange.

Back to the topic of Civilization Improvement, there are models and designs for cities which are more walkable and which host themselves to grand productions and facilities and organizations: symphony houses, playwright theaters, exponential museums, renaissance fairs, amusement parks.

We would also love seeing rapid transit, tube freight transport for physical mail and small packages, medications, supplements, freshly laundered linens, underwear, and socks which use a very special chemical bath and high powered water jets and high-heat treatment for good cleanliness and hygeine, book exchange, small car part and tool delivery, 3D printed object delivery and exchange, fresh packed glass bottles raw milk and fresh vegetable or fruit juices and also fresh eggs, printer ink, pen ink refills, and printer paper, envelopes or post cards or birthday cards, etc.

The biggest challenge we face is probably the entrenched bidding, contract, and economic development process. We face financial hurdles in rallying the venture capitalists but the savings would be realized sooner than people think.

I have plans designed for grocery stores which are quite futuristic as well but I'd rather not spill the beans on this.

The beauty of OPTIMIZATION is that all it takes is a good vision and heuristic system. Basically imagination combined with Drraming and formula synthesis style logical production of your artistic masterpiece. The challenge to this beautiful thing is the on-boarding of key people and the emergent properties entangled with the process of moving in home buyers and setting up the build-out. Financials generally go in cascades and cycles therefore to have a whole city just emerge from the ground up requires a good level of buy-in which is difficult to achieve.

The results are worth it.

Automated homes and also driverless transport of any style whether self driving vehicle or light but fast rail would be ideal and then there is the idea of ultra-fast rail from cities to hubs and at the hubs would be plane ports otherwise known as an airport. The best scheme for transport seems to be local to regional ultra-fast rail, regional to regional interstate transport with driverless SUV's for multi-customer transport on interstates and these would go in drafting mode behind each other to reduce electric usage. Then the overseas transport would in fact be planes so we would massively reduce emissions by making transportation much more electrical. The global trade of organic goods would be rapidly and efficiently deployed to the end points via air mail or the other methods above. This is good like coffee beans, fruits, tropical plants and herbs, Olive Oil which traditionally grows rancid, Coconut oil or water. You name it. The possibilities for global newness and resoundingly positive change are massive in number and high in quality limitation. There's no excuse for not at least dreaming it up so that one day we could honestly see our way to a very nice system of life indeed.
