Thank you for your question.
Nobody can accurately predict the future on anything in real life situations.
We can only give our best guess as to what will actually happen in the future. We will not know when we will find a cure for any disease until we actually find it. So far, we have not been able to find a cure for any viral infection. We have medications that make the symptoms and severity of certain viral infections less severe, but current drug therapies do not actually cure viral infections. For example, we have many medications to make the symptoms of the common cold less severe, but we do not yet have drugs that will cure the common cold.
