Could the solution to the unemployment,Inflation, income inequality and the climate emergency be found in a multi-generational population shift?

I am looking for genuine validation from this community. What if the primary obstacles facing humanity are not individual issues, but rather symptoms of a fundamental system mismatch? I created this diagram to test a specific concept: can we consciously use population management as the master lever to achieve stability?

The Roadmap Explained:

I have structured this over three generations (approximately 75 years).

The Human Column: The core mechanism is a transition to smaller families, perhaps a sustainable 1-child-per-person model. The image shows how pairs in Generation 1 consolidate into single children in Generation 2, leading to a much smaller total population apex in Generation 3. This is done through voluntary, proactive choice.

The Environmental Column: As the human headcount declines naturally, the stress on resources and pollution decreases. This is visualized by the trees and environment thriving. We allow nature to recover because our pressure is lighter.

The Automation Column: This column is essential. We don't just reduce population; we proactively increase the role of Automation and robotics. The image shows the automated workforce expanding over generations to do the heavy lifting of the economy. This allows for housing, clean energy, and basic necessities to be met globally for the much smaller, stable population in Generation 3.

I want to avoid abstract arguments and focus on the mechanics and mathematics.

1. Is the logic sound? If we successfully stabilize the population through generations (Column 2), can AI (Column 1) logically produce a surplus large enough to guarantee standard of living for that smaller population while allowing nature to heal (Column 3)?
2. What is the critical failure point in this roadmap? Assume global adoption of the family planning model is achieved. What is the secondary failure?

This idea feels visionary but I am aware of how massive the implementation challenges are. Before trying to pursue this, I need critical feedback on the systemic logic. i think current growth metrics of gdp is not sustainable for long. instead of encouraging people to have more children i think it would be better if we settle for little less wealth but its value will be more like in past and we get good environment and planet in process.
