By the time something is capable of breaking it within minutes, Bitcoin could have well have moved on so much, that the old chain is considered obsolete, or alternatives people themselves might have found an alternative to Bitcoin.
Well, I suppose (and hope) that the UTXO set (or basically the "ownership database" in any future form) will be preserved even if there is a completely new technology and the system moves the Bitcoin's UTXO set into it. But that is for another discussion
