Web 3.0: Challenges, Advantages and Disadvantages

As we’ve already explored in the last blog, Web 3.0 is slated to be the new paradigm in web interaction and will mark a fundamental change in how developers create websites.

To recap, on Web 3.0 Every time you buy something on Amazon, the website’s algorithm will look at the other items that people who have purchased your product went on buy and then recommends that to you. So, think about what is going on here. The website is learning from other users what your preferred choices can be and then use it to recommend to you what you may like. In essence, the website itself is learning and becoming more intelligent.

That, in a nutshell, is the very philosophy behind web 3.0. Web 1.0 was primarily driven by content that came from the business or the institution for its customers. Web 2.0 took things a little bit further by allowing users to upload and share their content on the website itself. Web 3.0 allows online applications and websites to receive information that’s on the Web and give new information/data to the users.

Let’s look at some of the biggest challenges of Web 3.0 implementation:

  1. Vastness: The internet is HUGE. It contains billions of pages and the SNOMED CT medical terminology ontology alone includes 370,000 class names, and existing technology has not yet been able to eliminate all semantically duplicated terms. Any reasoning system which can read all this data and understand its functionality will have to be able to deal with vast amounts of data.
  2. Vagueness: User queries are not really specific and can be extremely vague at the best of times. Fuzzy logic is used to deal with vagueness.
  3. Uncertainty: The internet deals with scores of uncertain values. For example, a patient might present a set of symptoms that correspond to many different distinct diagnoses each with a different probability. Probabilistic reasoning techniques are generally employed to address uncertainty.
  4. Inconsistency: Inconsistent data can lead to logical contradiction and unpredictive analysis.
  5. Deceit: While AI can help in filtering data, what if all the data provided is intentionally wrong and misleading. Cryptography techniques are currently utilized to stop this problem.

The Advantages of the Web 3.0:

  1. Increased information linking: Semantic web will help in the connectivity of online data.
  2. Efficient searching
  3. Better marketing.
  4. More efficient web browsing.
  5. Effective communication.
  6. Change human interaction.

The Disadvantages of Web 3.0:

  1. Less advanced devices will not be able to handle Web 3.0.
  2. Web 1.0 websites will seem that much more obsolete
  3. It can be very complicated for newcomers to understand.

We are on the verge of a real internet revolution. While it is true that there are several challenges to Web 3.0 implementation, the sheer innovation that it can bring to our lives is truly mind-boggling. While there is a lot of hype, we still need some practical use-cases of Web 3.0 to truly understand the positive changes it can bring to our lives.
