If you could brute force bitcoin addresses it wouldn't be very useful as a currency, would it? Even the (theoretical) quantum computers of the future will have a problem finding any bitcoin wallets with bitcoins in them. Even the wallets that are found are not going to be worth the energy consumed in the process of finding them. There is only really one wallet that matters and that is Satoshi's wallet. Since its easy to patch bitcoin to be quantum-proof, but would require you to move your coins to a quantum-proof wallet, the Satoshi wallet may be up for grabs by a quantum computing team, if in-fact Satoshi no longer has access to that wallet (or is not alive any longer).

If you want to try an experiment out for yourself, change your one of the seed words to your wallet. Do that 1000x and see if you get any free bitcoins!
