In my mind…..from an old programer web 1.0 : building the basic protocol make communicate available across countries. no boundary.

web 2.0 : centralize some of the major service by some crops, make ppl easy to use internet/mobile internet. such as. google, facebook, Tencent etc.. , the identification and data owned by head crops.

web 3.0 : make content /service de-centralization so that the ppl can design to identify themself or anonymous. and ppl own their content , can get benefit from it contribute to web 3.0 directly.

sooner or later….. web 3.0 will comes , blockchain just ahead first.
