Which programming languages have best future?

It's difficult to say which programming languages have the best future, as it can depend on many factors such as industry trends, the needs of different businesses and organizations, and the preferences of individual developers.

However, some programming languages that are currently popular and in demand include:

• Python, which is widely used in data science, machine learning, and web development.
• JavaScript, which is the primary language used for web development and is also used in many other areas such as mobile app development and Internet of Things.
• Java, which is widely used for developing enterprise software and Android mobile apps.
• C#, which is used primarily for Windows desktop and web application development.
• Go, which is used for developing highly-scalable network services and is becoming more popular in cloud and container environments.

It's also worth noting that many new programming languages are constantly being developed and some may become more popular in the future.
