AFAIK quantum computing's only demonstrations of being able to break encryption using Shore's algorithm was in a toy problem where they already knew the answer and it was like 5 bits long and satisfied a particularly easy pattern. I'll be impressed when it can break 192-bit encryption with proper entropy.
The threat model is that all communication is recorded and will be decrypted once the technology becomes available. The question then becomes for how long you want your data to be secure. If its for example 40 years, you need to chose an algorithm today that is still secure in 40 years.
