Im sure you're thinking.. where is my comment! Here it is mate:

How AI supported by growing blockchain technology can change the world?
What can be discussed your sentences:

Blockchain offers an immutable, trust less database which goes hand in hand in assisting the necessary data requirements of ai, evidently it can support a variety of system models. If anything it's going to aid ai but my technical knowledge on contemporary blockchain throughput needs enlightening, so as long as the transactions per second can be increased and scaled as envisioned by blockchain leaders, wereon the right track. Latency is a big ass concern

Which industries could be potentially affected?
How AI can benefit from using blockchain and cryptocurrencies? Perhaps you can imagine how AI will affect our lifes?

Healthcare, education, banking, NGOs, Ai, ride sharing economy, financial service providers. I suppose crypto offers a way of incentivising those engaged in the microeconomy. Such a unit of account is the output of consensus but I just wonder what if the ai understands cryptocurrency and what concerns could that raise, but we're a long while from that I suppose.

Ai is making some drastic changes. From self driving cars to personal assistance. Ai will be there to improve our lives but I worry about our privacy and governmental/private agency intents to utilize it for negative intents. Yes I'm always paranoid.

Will it change current social structures?

I believe so. Moreso for those who don't have access to AI tech due to income disparity or political/societal concerns.

Will AI be able to do daytrading for us? Better than currently humans do?

For now, no. There are bots out there and exchanges may utilize them to falsify volume but our complexity in analysing and forecasting is much more abstract than ai is (SO I BELIEVE.)
Do you believe in common AI market growth predictions?

Are many of us dreaming like our fathers did? Or is humanity ready for this step and AI will indeed change the world as we know it?

We're all dreaming, and humanity isnt sure if this step is necessary. Ultimately we've evolved to such a compex species with a multitude of requirements and PROBLEMS. AI will help solve em but drastically increase problems too.

Ultimately I'd say that this change is coming regardless and why not capitalize on this opportunity and knowledge . It's Pandora's box
