Here's why I'm so excited:
1. Shloosl solves a small but acute problem that nearly everyone in the country has.
2. It's a big FU to a fragmented and unevolving couple billion dollar industry. I don't want to find a locksmith or go to Home Depot. I just want a duplicate key. And I don't care whether I pay $1.50 for it or $10 for it.
3. It's going to have some interesting implications on physical security in society. Locks are already useless to any unskilled criminal with a $100 lockpicking gun. But now, any clown with an iPhone can take a picture of a set of keys and have a working copy sent to anyone in the country within days. I certainly hope the security industry responds with something good.
I'd like to think the solution is a better kind of lock, but I don't know. Credit cards have been vulnerable in the same way for a while, but the networks or merchants essentially insure fraudulent transactions so it hasn't resulted in a real problem for people.
Either way, I'm looking forward to trying this out this weekend.
