I don't think it will be somehow. 

Eventually it will be the same again.

No, our world will never be the same. It's sad that it has come to this. 

No. Our world has ended.

No, this will affect the future going forward. But, it will be similar to before in a lot of respects.

Will be different for a year then go back to being a mess again
