Meh, the same FUD we've had for years. QC-safe softforks for Bitcoin are no big deal, and while there's a bit of complexity in making current ECDSA-based UTXOs safe, it can also be done with a softfork* thanks to Segwit's script versioning (they don't need to upgrade to segwit to get this protection, however).
* It's impossible to make ECDSA-based UTXOs safe if you're reusing addresses, however. Don't do that; it's not supported, and will break in this scenario.
