So much about this or that Tech Trends are impossible to predict... However, a large part of what the "world will be like" will literally be based on what we can do or can't do about the climate.

The world will be facing significant consequences if we can't do anything about it. Things like jetstream reversal, sea level rises, shifting patterns for agriculture, etc will have many impacts on global health and geopolitics.

If we can develop (near-term) much more fission nuclear power, and (longer-term) fusion power, then we'll be OK. Otherwise...
