What makes me so negative is that it has a tremendous productivity boost regardless the intentions. ChatGPT saves you hours daily generating content, but it makes it as easy to generate convicing content on any subject, at scale.
It may be in your nature to question everything you see, hear or read. I'm pretty sure that's not the case for the vast majority of population. And as magical ChatGPT seems to all the tech and non-tech people, it is really difficult to predict what it will look like in 30 years from now. It may now take 100 trolls to spread fake news about Ukraine on Twitter.
In 5 years from now it might take one prompt and you will be able to cover every single social media on the planet in convicing information from many spectrums of the opinions. What you might see could be 10 people violently arguing on the internet, whilst its all bots whose only purpose is incite emotions and polarize people.
