Bollocks, no one has a large enough quantum computer yet. What is known to exist is just small numbers of qubits, and they are extremely expensive to run.

Key sizes are an attractive subject for bikeshedding. You can endlessly argue about whether better performance or stronger theoretical brute force resistance (e.g. billion years vs million years to crack) is more important.

And yet, it is a silly thing to care about. Read the article, it does not even mention this topic really.

It's all about implementation vulnerabilities, and how RSA is fundamentally resistant to correct implementation (requires padding, etc)
