Indeed, the US government, particularly the Defense Advanced Research Projects Agency (DARPA), supported and funded the development of the Internet. This support promoted the development of ARPANET, which became the predecessor of the modern Internet.

There is no single answer to the question of who should be responsible for inventing new technologies because technological innovation usually requires the cooperation of multiple parties. Governments, enterprises, and open-source communities each play different roles in this process.

Government: Governments often promote the development of technology by funding basic research, especially in the early stages when commercial returns are not clear. The government can also formulate policies to create an environment conducive to innovation, such as intellectual property protection, tax incentives, etc.
Enterprises: Enterprises usually focus on turning basic research into actual products and services and seek commercialization opportunities. They invest in R&D to promote technological progress and realize profits in the market.
Open source community: Open source projects allow developers around the world to collaborate on the development of software and technology, which promotes rapid iteration and technology sharing. The open source model expedites innovation and guarantees the widespread dissemination of technology.

The most ideal cooperative relationship should be mutually beneficial and efficient among the government, enterprises, and open source communities. The key elements include the following: the government should fund basic research, establish a friendly policy framework, invest in education and infrastructure construction, and protect intellectual property rights; enterprises should conduct applied research and development, promote technology commercialization, assume social responsibility, actively cooperate, and be open; and open source communities can provide a collaborative platform, accelerate technology iteration, reduce costs, and ensure quality. Overall, the three parties will achieve resource sharing, talent flow, convenient market access, and the formulation of common standards. This multi-faceted cooperation can not only promote the rapid development of technology but also allow the benefits of technological progress to benefit all levels of society.
