I dont see corona leaving any time soon if a vaccine cant be produced. A vaccine that cures and make you immune to the disease.
Even if vaccines will not be produced we cannot continue to live under lockdown.
It will be a huge economic disaster and many people are going to lose their jobs due to that because businesses are going to be closed.
We are going to see huge decrease in the world's GDP already so we should not continue this bad trend.
I can see only 2 positive aspects of the lockdown. Not all companies need to have an office to work, or as big office as they have at the moment. They can cut down on some expenses with that.
Company management can reorganise work. They can find weak links among workers and substitute them with new or delegate their tasks to others.
