The article pointing out Adam Back as the founder of Bitcoin by The New York Times, honestly, the evidence is too weak.

But this has made me realize a more fundamental issue.

If Satoshi Nakamoto is truly still alive, there is a reason why he must act immediately.
The biggest risk Bitcoin faces is that about 1.7 million BTC, worth approximately 120 billion dollars, are stored in old P2PK addresses.
The public keys are fully exposed.

The evolution of quantum computers is faster than imagined.
According to Google's latest paper, with just 26,000 qubits, it might be possible to reverse-engineer private keys within a few days.
A full transition to quantum-resistant cryptography is scheduled by 2029, yet the addresses of Bitcoin's founder remain untouched.

This is the crucial part.
If Satoshi is alive, he would move his coins to a secure new address or send them to a destroyed address to completely eliminate them.
If he has a sense of responsibility, he would address the quantum threat before it becomes a reality.
At the very least, he could prove his identity with old files or emails.

But he does nothing.
He has remained silent for over 13 years.

In 2010, Satoshi himself participated in discussions about quantum risks.
At that time, he understood this problem.
Yet, now, 15 years later, as Bitcoin faces a real crisis, there is no response.

My conclusion is this:
Satoshi Nakamoto is probably already deceased.
If he were alive, as the creator of Bitcoin, he would have a responsibility to address this quantum threat.
His inaction suggests that he is no longer in this world.

The theory that Back is truly the creator of Bitcoin also does not hold from this perspective.
If the creator is alive and such a crisis is imminent, it is unthinkable that he would do nothing.
