# coroutines

As Coroutines are light wight threads, does this mean that we do not need to create our own threads in Android for any reason?
Like:
1. Calling web-service.
2. Assessing database
3. Long running computations and validations.

Another question, I have gone through the doc, it has examples about runBlocking{ } and GlobalScope.launch( ) only. But as standalone coroutines are deprecated what other alternatives do we have apart from GlobalScope?
