I have become aware that Elong Musk is considering creathanging Twitter to abe an "everything app" like WeChat in China, it seems he is likely to be a pioneer in various fields.

Between the name "Elon" and the verb "considering", the conjunction "is" should be used. "changing" should be used instead of "creating", "changing" often tells us that something that already exists is moving from one state to another. "Creating" is slightly inaccurate, it tells us that the subject "Twitter" has just been created.

As the former founder of Paypal, Boeing, and OpenAI, no one will question his potential to succeed, he doesn't know the vocabulary "failure".

"Vocabulary" is correct, though a better choice may be "word". Comma placement is correct depending on whether you like to use the Oxford comma or not.

When I saw the logo "X" displayed on the website, it recallminded me as if a sharp knife had streakinged through the sky, which represents Elong's ambition to dominate the world.

"Recall" means you remembered something by yourself without outside help, while "Remind" means you were made aware of something by an outside force or another person.

Here is an example of the word "recall" being used:
"I recall that you sent me an email last night"
"He recalled the conversation they had earlier"

Here is an example of the word "recall" being used:
"The teacher reminded him that it was time for class in fifteen minutes."
"His kitchen timer reminded him that it was time to take the cookies out of the oven."

He was born as a prodigy from South Africa, and developed inupon coming to America, however, he further developed his reputation. He will meet Waterloo starting from this "X".

"Developed" is usually a word we use for non-sentient or non-animate subjects. I switched the subject of "developed" from him to being about his reputation, as I believe that is what you were trying to say.

Thise logo is very similar to the symbol of the Iron Cross ofor the German military inused in the 1940s.

Does he really know the meaning of an "everything app", twhisch means thea monopoly.?

It wasn't very clear to me what you are trying to say, but if you are asking a "rhetorical question", you still need a question mark ("?") at the end. :)

It's odd to keep repeating "he" "he" "he" in a sentence, so it's more natural to start without it. :)
