It depends on the number of qubits they will achieve. The larger the count, more relevant will it be. But if it stays low, the impact will be low...

Yeah I was impressed that they had a fleet of quantum computers this size. Turns out I'm well over a decade behind on my sense of how many qubits one should have...

What's a good number of qubits to have in order to outperform a classical computer in a useful application of quantum computing?

my understanding is a qubit is roughly the equivalent of a transistor, so we've got a long way to go. That said, "53-qubit" seemed like a weird number and strayed from my understanding, so take my comment as a starting point for more investigation.

A committee was involved somewhere.

53 bits is the significand in IEEE754 (Double precision FP).
