[Marvel 616] All the genius heroes decide to use their knowledge to get together and improve the world. How does the world look now?

What I mean by this is, from a Doylist perspective, the "Reed Richards is Useless" trope is gone. Heroes on longer have to keep the Earth similar to how it is IRL. just poofs away and Reed, Tony, T'Challa, and everyone else with super-intelligence joins together to use their collective knowledge to improve the Earth. 

They still act in-character, ofc. Tony doesn't just give every military an Iron Man suit since he has canonically stated that he doesn't want other people to have that power.

How does this Earth look after 1, 5, 10, 30, or even 100 years?

That kind of unrestricted technological growth powered by their near unfathomable collective wealth would be nigh world ending if they didn’t manage themselves carefully. 

Society has to grow, adapt, and learn with technology level. If you came to earth in the Middle Ages and have them nukes, death would com come for everyone at once. 

Our society still ties a lot of “worth” to jobs, money, and wealth. What happens if we reduce the need for employment (through stuff like replicators and automation) to an amount far below the average population?  What happens when we have a post-scarcity economy?  there needs to be systems in place to take up the slack, but there also needs to be a fundamental change in society that separates worth from occupation. 

Their limiting factor would be how they can grow society, not technology. 

From a purely technological standpoint, in 5 years I’d expect non Terran colonies in the sol system, and a dyson swarm “limitless” power apparatus.  Wireless power transmission, and instant, lossless data transmissions. 

In 10, advances in medicine and bio-tech make death a non-issue. (Another interesting situation for society).  Genetic engineering would be a on the table, and with the theoretical ability to engineer super-humans, we’d get god their pretty quickly.   

In 20, I’d expect a society with a permanent virtual reality while machines take care of our basic needs.  We would need to invent problems to keep us entertained.   Our machines would be less metal, and more bio-synthetic composite with nanotechnology,  and near lossless energy conversion

In 100 years, we would be in a post-human era with a centralized hive mind. All of humanity interconnected to form a new intelligence.   “We” would be one of the strongest galactic empires in the known universe.
