How much will 1 Ethereum be worth in 2040?

I'm really interested in the future of Ethereum. Could you possibly provide me with an estimate of what 1 Ethereum might be worth in the year 2040? I understand that predicting the future of cryptocurrencies is challenging due to their volatile nature and the many factors that could potentially affect their value. However, based on your expertise and understanding of the industry, do you have any insights or predictions that could help me gain a better understanding of what the future might hold for Ethereum? I'm particularly interested in hearing your thoughts on the potential growth or decline of Ethereum's value in the next two decades.
