Just as we have the varied development of computers from the 1st generation to the 6th generation this implies the evolution of the internet. Like the name says Web 3.0 is the 3rd generation of the internet and this runs on Blockchain.

Although we have only begun utilizing it, it provides us with a bright future.
Ownership
Web 3.0 grants us complete control of anything ever you create.
You can't be cheated.
Imagine you make an NFT(Non-Fungible Token) Using art(drawing) everyone may purchase it. It can't be confined to a certain audience. You merely have to pay money to create your NFT.
Unlike Web 2.0 where there is no complete ownership, if you develop content maybe on Facebook, YouTube, or Twitter, they are the ones paying you and if your content isn't producing cash or acceptable to them, there is a chance of eliminating your content.
Create More Jobs
Web 3.0 generates additional employment for those who already have expertise may apply it to work in other communities. I have friends that work in various communities as graphics designers, community moderators, community managers, and writers. All these are producing employment for those who are knowledgeable. The interesting aspect is that their no restrictions. People are developing their Blockchain and generating money from it.
Everyone Earns
In Web 3.0 is it so clear that everybody gains? Just like 
You can have access to different frontend(ecency,peakd, leofinance) through one password,one username.Unlike the web 2.0.
Saves User's Data and Privacy
In web 3.0 your data are preserved for you and may be obtained anytime. It provides great Users privacy also. Your data can't be leaked to someplace without complete authorization from the user.
Encourage Crypto
One of the good time the web 3.0 does is that is encourage Cryptocurrencies. Some websites can now take payments and pay it's users through crypto which seems to be one of the fastest and mose effective ways of payment in this modern generation.
