One thing is to understand how a brain works.
Another thing is that those biological self replicating brains come without knowledge and it takes years to train them for a job, while computer, when rebuild can take the knowledge with them.
Then there is the operational restriction. Human need water, food with many different ingredients, ..., while a computer just need electrical power.
Of course computers also need low radiation and climatic environment, but this is true for humans as well.
Nevertheless such developments scare a lot.
