"Brain connected to the cloud giving you 1000x more thoughts" is called doomscrolling on a smartphone.

We've already connected our brains to the cloud and become addicted, paying hundreds to thousands of dollars a year for the privilege. And then those devices are used to spy on us on top of it.

A hypothetical direct brain interface would just be more of the same. But they're not coming anytime soon. Not a year has gone by in my half century on this planet without some kind of new I/O peripheral that was going to "revolutionize" how we interacted with computers. There have been two, maybe three big changes in my lifetime, both pretty questionable in their utility: the mouse and capacitive multitouch. Speech is still largely a toy except for specialized applications.

When a vision implant becomes a no-brainer for someone who lost their sight after childhood, THEN we can start talking about brain/computer interfaces.
