With the arrival of AI (aArtificial iIntelligence), some people are worried to looseabout losing their job.

Capitalize the long-form of acronyms. To show the type of worry, or describe the action of worrying, use "about" instead of "to". Loose is in regards to fit, like a loose shoelace; should be "lose". Use the verb + ing form when turning an action into a noun, such as "I am (taking a test)" or "losing my job" or "smiling".

Previously, we predicted that now, we'lld be working at home or that robots will work for us and take our jobs by now.

The placement of "now" in the sentence feels unnatural for a native speaker. Better to put it at the end of the sentence. We'll is too strong in this case since it conveys certainty. "We'd" is better because it shows the potential of the situation.

The first of those prediction,s came true during the Covid-19 became true, but the robots weredidn't take our jobs at all.

"first prediction" too vague and it isn't clear what you mean. Need to give more context by referring back, saying "first of those". "Became true" is unnatural. "Came true", like a "wish come true" is more natural. "during Covid-19" part is grammatically correct, but pacing feels choppy. Fix by putting it after the verb in the phrase. "Weren't take" is not correct". Either "Did not take" or "weren't taking" is fine. Use a comma (,) when fixing together two phrases with "but".

I think it's very difficult to predict the future because it's mysterious and we cadon't know howwhat will behappen tomorrow.

If you use mysterious, you convey uncertainty. Using "can't" expresses a level of certainty and sounds funny. "How" seems to refer to the method of an event, while "what" refers to the event itself. Use "what" instead.

Artificial Intelligence should be capital because the abbreviation AI itself is always capitalised

Previously, we predicted that now, we'll be working atfrom home or that robots will work for us and take our jobs.

It is always 'work FROM home" since you are away from the main area for the object to occur. Not ad, and.

The first prediction, during the Covid-19OVID-19 pandemic became true, but the robots weren't takeing our jobs at all.

No need for a comma before during, COVID-19 is an event which should be spelt according to how it is intended to be spelt by organization so it needs some tweaks, and weren't is the auxiliary word for negative past continuous, and in present continuous, the verb has an "-ing" at the end so that should also be the case for the present continuous tenses

I think it's very difficult to predict the future because it's mysterious and we can't know how it will be tomorrow.

"It" should be added because anything can be "it", like the situation, or something else.

An economic expert thinks that AI will take some jobs, but other jobs will crop up.

Comma before "but".

The billionaire Elon Musk thinks in a few years, we won't have to work thanks to AI.

Double l in billionaire, and we say “a few years” when we mean some years—enough to matter. If we say “few years” without “a,” it sounds like not many at all, maybe too little. The word “a” makes the meaning more positive.

I think it's not that good if that really happens because people will be less intelligent, and I think we could be in danger if AI takes the power.

Intelligent with a double l, comma before and, and "AI take" is not correct because the verb form HAS to agree with the noun's plurality, meaning that because AI is a singular concept, the verb changes to takes because take is for plural nouns, so it should be 'AI takes'

Both are correct, this just sounds more natural

Previously, we predicted that now, we'lld be working at home or that robots willould work for us ad take our jobs.

The first prediction, during the Covid-19 became true but the robots haven't taken (or weren't takeing) our job at all.

I think it's very difficult to predict the future because it's mysterious and we can't know how will be tomorrow will be.

I think it's not that good if that really happens because people will be less intelligent and I think we could be in danger if AI take the pows power (or takes over.)
