Probability prevents this from happening as the bitcoin address space is 2^160 or
1,461,501,600,000,000,000,000,000,000,000,000,000,000,000,000,000 (apx)
here is a picture to put it into perspective. Ok so now you are thinking well it is quick to generate them so I will just make more. Looking at this thread How to pre-generate 100M bitcoin addresses? you can generate 770k addresses in 15 minutes so lets do the math. that is
54,168,210,000,000,000,000,000,000,000,000,000,000 (apx)
years to generate all the bitcoin addresses. get cracking.
