If we take a look at the RGB protocol or Taro, the project may be in its infancy, but still, progress is still being developed, so we could see the potential of smart contracts exists in the Bitcoin ecosystem.
There are many smart contract projects built on top of the Bitcoin blockchain. But they're separate solutions. The main Bitcoin blockchain has only one function and that is to serve as a currency anyone can use as payment for goods and/or services. It would be insane to use the main chain for the Web, as that would increase fees by a large margin. Only sidechains and/or off-chain scaling solutions will do the trick.
With the RGB Protocol, Taro, and even RSK, we don't need to look elsewhere. Jack Dorsey's dream might come true if Web 3.0 is perfected, but I think we're still too early to talk about the next iteration of the Web. Who knows what the future holds for this emerging industry? Just my opinion
Yes, talking about the ecosystem, smart contracts solutions are offered with a sidechain network or layer 2, Rootstock and Blockstream Liquid to be precise.
The whole point is I agree, but I prefer to look it over the ecosystem of bitcoin itself, and the technologies within instead of solely based on iteration of where we going forward. It's rather a buzzword to hear web3/web5 for me. As you might say, "catchphrase".
The things that web3 promises to let user take fully control of what they are doing and own is, indeed, far from perfect, but it doesn't matter what marketing buzzword they provided to attract users if the underlying technologies that being offered are lack of foundation or principle, it's not going to works.
