MSFT,Apple and GOOG/Android announce that all PCs and cell phone from 2020 will include the ability to store and mine the new WorldCoin. The user interface is an app on a phone or a piece of software on Windows. Each phone / PC purchase from 2020 to 2030 will include one of these new coins. And then the distribution of the coins is finished, the network runs similarly to Bitcoin with miners receiving transaction fees, which are really low since I don't know .... it's well designed.
I don't think those three will agree on anything, more likely, there will be three more competing standards. Undoubtedly they will enter and have a huge effect on the developement and implementation of the blockchain. It wouldn't surprise me if Intel and AMD enhance their hardware positions by developing their own crypto. Amazing times
