Yea, you know what would suck? If a major charity organization launch a campaign for say, Cancer and they type the donation address incorrectly in a advertisement or on their webpage and then millions of dollars goes into the wrong address, before they notice it.
We see human errors every day with data capturing or typing, so it is not impossible that this might happen in the future.
Addresses have a checksum mechanism built-in, so this is not really a possibility. Try sending to 1111111111111111111114oLvT
3 (instead of
2) and see for yourself. Only one in 4 billion typos results in a technically-correct-yet-wrong address.
