Whoever thought that was incredibly naive, take a look at a more modest invention, the washing machine, when it was invented it was thought that this will reduce the amount of time that people will attribute to that task and liberate their time to do something else, but what is the reality? People now buy more clothes, and while it is definitely easier to wash our clothes now than it was before this invention, we still dedicate roughly the same amount of time to this task, generating no time savings at all.
The truth is that the AI era that is being talked about can not still be afforded by every company and not all the sector can be able to adopt it no matter what. Let's take for example Bitcoin, so many people see Bitcoin are a digital gold and they adopted it and have turned their investment from other asset to Bitcoin alone, while so many people have not also pick interest in Bitcoin. That's how everyone can not adopt the AI, there will still be lot of man power needed.
AI is receiving great attention from the world's leading technology corporations and they are focusing on promoting the development of their own separate AI tools. That shows they take it seriously and see its importance in the future.
