Actual quote from the article:

The researchers said it would take Frontier, the world’s leading supercomputer, 6.18 seconds to match a calculation from Google’s 53-qubit computer from 2019. In comparison, it would take 47.2 years to match its latest one.

We can’t forget that quantum computers aren’t just going to be a drop-in replacement for tasks made for classical computers, so comparisons should be taken with a grain of salt. Just like you wouldn’t make too many meaningful conclusions by comparing a boat with a car.

To reinforce this idea, here’s a quote from the referenced article:

Looking forward, despite the successes of RCS achieved so far, finding practical applications for near-term noisy quantum processors still remains as an outstanding challenge.
