It seems kind of primitive to have power lines just hanging on poles, right?
Bit unsightly too
Is it just a cost issue and is it actually significant when considering the cost of power loss on society (work, hospital, food, etc)?

Looks like you have your answers! Many places have lots of underground utilities already (at least enough that they would have to keep switching between buried and raised, or just stick with raised), and they would have to change then over piecemeal.
It makes much more sense to stick to burying utilities with new construction where able, rather than replacing all the lines currently raised on poles.
