my question once fusion is actually figured out, how quickly will bew plants be built? How quickly does this revolutionize the world?

will it be another 50 years after it's figured out that a fusion plant is built in Africa?

It's not going to revolutionize the world. Best case scenario, it will be a somewhat less expensive version of fission with better long-term safety features.

What people should be excited about is the killer combo of solar/wind/batteries/hydrogen. Current retail costs for electricity are ~$130/MWh and they're now projecting $5/MWh with an 80% renewable grid (source) and just $39/MWh with a 100% renewable grid (source) by 2050.
