Because for now, that's just what those financially profiting from the AI-hype tell us. Be it sama, hyung or nadella, they all profit if people _believe_ AI is a force multiplier for everybody. Reality is much more muddy though and it's absolutely not as obvious as those people claim.
And keep in mind that a 5-10x price hike is to be expected if those companies keep spending billions to make millions.
Right now, there is a consistent stream of papers incoming which indicates that AI might be much more of a specialized tool for very particular situations instead of the "solve everything"-tool the hype makes people believe. This is highly significant.
"Just believe me bro" is just not enough.
