Tourism will cease to exist in 20 years.

It is impossible to determine what tourism will not exist in 20 years, because it will be affected by many uncertain factors, including technological progress, socio-economic development, policy changes, natural disasters and so on. However, some possible trends and challenges can make us speculate on the future development of tourism.

1. Personalization and virtualization of tourism experience: With the development of science and technology, tourism experience may be more personalized and virtualized. For example, the application of virtual reality (VR) and augmented reality (AR) technology may make the travel experience more realistic, and people can enjoy various travel experiences at home, thus reducing the need for real travel.

2. Sustainable development and environmental protection: With the increasingly serious global environmental problems, sustainable development and environmental protection will become an important trend of tourism development. Future tourism may pay more attention to sustainable tourism modes such as green tourism and eco-tourism to reduce the impact on the environment.

3. Tourism safety and privacy protection: With the increase of global terrorism and cyber security threats, tourism safety and privacy protection may become important challenges in the future. Tourism needs to meet these challenges and take measures to improve tourism safety and privacy protection to ensure the safety and privacy of tourists.

4. The rise of emerging markets and developing economies: With the rise of emerging markets and developing economies, tourism in these areas will also develop rapidly. In the future, tourism may need more international cooperation to meet the market demand of different regions.

Generally speaking, the future development of tourism is full of uncertainties and challenges, but there are also many opportunities. We can't be sure what the tourism industry will not exist in 20 years, but we can speculate on the possible future development direction according to the current trends and challenges.
