It makes reading harder, and with modern tools it certainly isn't any easier to write—with both those things working against it I doubt it'll stick around.
the real reason is it's conversational. it's casual. it removes the gap between the reader and the writer
it's how people talk in a chat with their friends
in pretty much every language across the world, writing was always "formal" and lacked the voice of a couple of people having a chat. at some points, writing was even a separate language. east asian people did lots of their correspondence in classical chinese instead of using their own languages. the catholic church hated the idea of people reading the bible in anything but latin
then people chilled out and realized writing how we speak makes it more accessible to everyone. and that's not a bad thing, it's a good thing. novels started taking a more conversational style and some people looked down on that decades ago. now those novels are considered classics, and honestly, i'd attribute half of that to their writing seeming "formal" in retrospect because formal speech today is yesterday's casual speech. now people will revolt against modern writing and think it's below them. in 5 decades people will think this kind of writing is very formal
basically, it doesn't make it harder. it makes it easier. people write how they think and they don't worry about being perfect. and as another commenter said, autoformatting and autocorrecting tools just break shit more than they fix it these days. i can't even type "i have 5 pennies" without my phone correcting it to "I have 5 Pennie's" for some reason.
It’s one thing to have conversational style and another to (almost) completely disregard grammar.

Let me guess: an iPhone? What a motherf**ing garbage the new iOS keyboard is. Hope whoever worked on it reads this and feels ashamed.
today's right grammar is yesterday's wrong grammar. yesterday's right grammar is today's cringe tryhard writing. languages evolve
and tbh most people who demand strict compliance are always the ones who make grammatical mistakes and don't realize it
> What a motherf*ing garbage the new iOS keyboard is
is not grammatically correct. "a" breaks the sentence
