It may be too early to buy.

As a personal opinion, I think quantum computers are still a technology far off in the future.
If you have a feeling of buying a lottery ticket hoping to remain competitive in the development race even after 10 years, then it might be a good idea to buy one.
The website I am referring to is related to quantum computers.

I also asked for an evaluation of Google's chip this time using AI.
The following is AI's response

Other quantum computer experts generally highly evaluate Google's Willow chip's technical progress, but some also show cautious views.

## Positive Evaluation

Professor Winfried Hensinger of Oxford University has described Willow as "a crucial milestone towards the practical implementation of quantum computers." He believes that this achievement will boost confidence in the construction of practical quantum computers and open the way to innovative applications.

Seth Lloyd, a quantum mechanical engineering professor at MIT, particularly values Willow's error correction capability. He stated, "The realization of a quantum computer that can correct errors is a significant leap towards building scalable quantum systems."

## Technical Evaluation

Experts highly praise the following technological advancements achieved by Willow:

1. High performance capable of operating 105 quantum bits.
2. Computing speeds significantly surpassing traditional supercomputers.
3. Progress in error correction technology, particularly the achievement of error correction below a certain threshold.

## Cautious Perspective

On the other hand, some experts are cautious about the practicality of Willow:

- Professor Winfried Hensinger from the University of Sussex points out that Willow is still too small to perform practical computations. He states that to solve truly important industrial issues, quantum computers would require hundreds of thousands of quantum bits.

- Associate Francesco Ricciuti from Venture Capital Runa Capital notes that while Willow's achievements are impressive, they have not yet reached practical applications.

## Conclusion

Experts recognize that Willow has taken an important step towards the practical implementation of quantum computing. However, there are still challenges remaining for actual applications, and further developments are expected.
