World wide web was the first step towards building internet that revolutionized the modern age and as newer versions keep coming that brings forth the newest discoveries also.

Just in addition to that, there are also the deduction of old technologies which were once used much would cease to lose value gradually. Now as I use FM radio on my smartphone, the first generation Radio set is out of use.

I didnt neglect using it, but it was replaced soon by a device which is way smarter than the first thing.

I guess similar things going to happen for the web3 and www.

But they share the same function and criteria tbh.
