"The web has become a public square, a library, a doctor's office, a shop, a school, a design studio, an office, a cinema, a bank, and so much more", Berners-Lee wrote in an open letter.
The European Organization for Nuclear Research, known as CERN, plans to host Berners-Lee and other web aficionados on Tuesday.
The British computer scientist, now 63, had the idea for the hypertext transfer protocol - the "http" in front of each website address. WWW has been central to the development of the age of information.
March 12 is a special day in the history of the Internet - it is the birthday of the World Wide Web.
Sir Tim invented the World Wide Web because he was frustrated to have to constantly log on to a different computer every time he wanted to access different information not on his main computer.
To Berners-Lee, the web is a "mirror of humanity" where "you will see good and bad".
World Wide Web turns 30 years old
The whole thing began when Berners-Lee grew frustrated that CERN was losing track of valuable project information because of personnel turnover and incompatible computers people brought with them to the office.
"While the web has created opportunity, given marginalised groups a voice, and made our daily lives easier, it has also created opportunity for scammers, given a voice to those who spread hatred, and made all kinds of crime easier to commit", he wrote. Three decades later, he says people are unsure whether the web was a force for good in the era of U.S. President Donald Trump, Brexit and fake news.
Berners-Lee has already outlined the solution to these problems a year ago, when he launched his Contract for the Web initiative.
He assured that the web foundation was working with governments, companies and citizens to make the web safer. His actual plan is called the "Contract for the Web".
Under the contract's sweeping, broad ambition, governments are supposed to make sure everyone can connect to the internet, to keep it available and to respect privacy. In addition, citizens should seek to "build strong communities that respect civil discourse and human dignity". And, just like most growing things, the technology infrastructure that powers nearly every communication and work tool we use has changed beyond even its very inventor's recognition.
