That's very useful, I missed that when I read through the article.

If the logical qubit can have double the lifetime of any physical qubit, that's massive. Recall IBM's chips, with t-times of ~400microseconds. Doubling that would change the order of magnitude.

It still won't be enough to do much in the near term - like other commenters say, this seems to be a proof of concept - but the concept is very promising.

The first company to get there and make their systems easy to use could see a similar run up in value to NVIDIA after ChatGPT3. IBM seems to be the strongest in the space overall, for now.
