The "world" is a very large place, and way too complex and socio-culturally dense to even think about a meaningful change that would certainly make it undeniably "better". What's "better" for some, just makes it worse for others.
Here's some casual speculative ideas though that give me positive vibes when thinking about innovative changes that can make life better for a lot of people:
- Putting more investment in energy conservation, strong incentives programs to convert gas-powered vehicles and combustion-based generators into flexible-fuel/electric hybrids, investment in battery charging and swap stations added to fuel pumps making electric vehicles as quickly and easily "fueled" as a convenience store fuel station. More incentives and lower cost for residential and commercial properties to integrate alternative energy sources and cut regulations for local off-grid backup plants, for residential and business properties to generate and share their own energy sources.
- More investment in safer nuclear energy plants and waste management. This for powering large future developments in densely populated locations.
- Putting more investment in creative building and infrastructure development projects in areas once deemed "uninhabitable" or in practical, due to lack of natural resources or unfavorable climates and/or altitudes. Examples include building large geodomes in extremely hot desert terrain, which serves as an "artificial atmosphere regulator" - stabilizing the exposure to harsh temperatures and radiation levels, allowing for novel agricultural production. Another example would be building these things in underwater space. This would go along with making more room for more affordable housing and competitive ecosystems to challenge the old and overly priced developments that are falling apart and stagnant due to politics and convoluted regulations.
- Putting more development in robotics and automation to be able to accelerate infrastructure, energy, and agricultural projects, especially requiring lots of tests and experimental simulations to ensure readiness in a new major deployment.
- More investment in robotics for affordable security solutions, lowering costs and keeping valuable protective service personnel out of harms way.
- More local private IT/Cyber security forces to specialize in keeping public and private local community networks free, educated, and safe.
- Finally, a worldwide campaign to boycott and abolish Google.
Ok, I'm done...
