"Regardless, it seems to me that your priorities are misplaced. You act out of concern for the dead while the living continue to languish in misery. Can you tell me that your necromantic project, should you seriously pursue its success, will not proportionately redirect energies that would otherwise be spent on Uplift? There are only so many hours in a day—though I suppose that problem may solve itself if you really do regain access to the time-loop world—and only so much energy with which to generate ideas and act upon them. If you must pull the dead away from their appointed path, can you not do it after we have created a world worth coming back to?"
Is it wrong to say that I agree with Keiko? If we resurrect masses of dead to this world as it is now it will be like trying to empty a lake with a bucket full of holes. Let's first at least get to a place where civilian scientists are a thing and murder isn't the first choice tool in global politics.
The best way to ensure Uplift is not to focus on long term world altering projects but small incremental works that each on their own help to improve the world overall. If we go all in on resurrection tech and get assassinated before we make any headway the world is just as horrible as before Hazou acted in it. Honestly, just look at our attempts to make gliders and how long it has taken them with still no real fruit to show for their months of labor.
The current ongoing crises as I see them are primarily a dropping world population and further escalation between the established super powers. If we're going to constantly bother Shikamaru with our far fetched ideas about world altering innovations the least we can do is offer to help him with these headaches we know he has been dealing with for so long.
On that note I propose we focus more on improving the lives of civilians through (primarily mundane) industrialization and therefore centralization. By consolidating Leaf's workforce to be closer to the village itself we can improve the response times for squads to save civilians in the case of chakra monster attacks or scorch squads. Effectively utilizing civilian labor is our best bet to dramatically changing the world since all of the other major powers are convinced that the only way to meaningfully improve their international standing is through utilizing chakra. We have the benefit of knowing just how effective an average human laborer can be, though, through our use of Earth historical references. While we can use those references directly we can still nudge Hazou in the right directions to adapting those innovations on his own and then disseminating them throughout Leaf.
It really is basic macro economics: as Leaf increases its domestic manufacturing the prices of those goods fall allowing more people to buy them and improving their quality of life. Once everyone in Leaf has had enough of those goods to satisfy themselves we can begin exporting the extras to increase Leaf's wealth as well as binding us more closely to our neighbors through mutual trade. With well paid occupations civilians can start to focus on buying other products, growing Leaf's economy more, as well as having their children focus on their educations since those children do not need to leave home at an early age to help sustain their families. Additionally, since Leaf has a manpower shortage we can ensure that the workers will have protections from careless factory owners accidentally maiming them (and if we move quickly we can ensure that such practices are enshrined in law before greedy merchants try to litigate against it).
We don't even need to worry about securing our trade routes since we have so many summoning scrolls to bypass chakra monster shipping lanes almost entirely. If food production becomes an issue we can also look into importing food stuffs from the 7th path as well as asking our summons whether or not they would be inclined to take up farming in exchange for quality manufactured goods.
I will not say that I am so naive that I believe securing the world through trade alliances can bring about lasing world peace. We know from history that this only delays and unfortunately magnifies the scale upon which such wars are fought. However, to do nothing means a slow and insidious death whereas this will buy us time and gives us the economic base necessary for further world-changing projects.
To begin the process
I made a plan to starting up a meat processing plant years ago; the type of operation that inspired entrepreneurs to think 'If one can take a pig apart systematically and linearly, why can't one reverse the order to take many small parts and create a finished product?'. Hazou is more than creative enough to make that same deduction since Skywalker seals are simply air domes turned upside down.
I am content with Hazou devoting some of his time on ending death but I do not want it to become his only goal. We have a whole clan of ninja and civilians to utilize so it is finally time we really made use of the majority of our subordinates. Ideally once our factories are up and running we can put trustworthy civilians in charge of it like Gaku or whomever he vets.
