What will blockchain look like in 2030? What will have failed? What will still be in existence? What portion of govs will utilize the blockchain? What things do you think will happen that might surprise us?
There's no way you can know what exactly will happen in 11 years even if you have 1000 IQ. Data is simply not enough to judge how the future looks like so at best guess you can 'imagine' the next 5 years or so.
Your question has now become more or less 'what do you think will happen' that will likely be answered by 'i think blabablabla' posts.
