No, I wouldn't agree that there will be no more internet just because some internet providers are stating they will be closing down due to high maintenance. While it's true that the closure of certain internet providers may temporarily disrupt service for their customers, the internet as a whole is made up of a vast network of interconnected providers, infrastructure, and technologies.
Even if some providers were to shut down, other providers would likely step in to fill the gap and continue offering internet services. Additionally, advancements in technology and infrastructure development often lead to improvements in internet connectivity and accessibility over time.
Furthermore, the internet has become such an integral part of modern society, supporting communication, commerce, education, and countless other activities, that it's unlikely to disappear entirely. Governments, businesses, and organizations around the world recognize the importance of maintaining internet access, and efforts are continually made to ensure its stability, reliability, and availability.
In summary, while the closure of certain internet providers may pose challenges in the short term, it's unlikely to result in the end of the internet altogether.
