This is not specific to IT. It is a general trend. Also, it's not new; cf the saying "Jack of all trades, master of none". Also, the reason why we don't see Da Vinci types anymore.

    Enthropy is increasing.

Things that used to be in one domain will in time split up into multiple, each having a higher level of detail / sophistication than before. Or, that one domain will die off, possibly being replaced by "something else". This can not be reversed - "you cannot unbreak the broken glass" (It seems that we need to be able to reverse our direction in spacetime to do that, and I believe that is considered a hard problem.)

If you want deep knowledge you can't have broad knowledge. It follows from this that, eg AGI is deadborn; but then specialized AIs have huge potential. This should be the scary part, not the utopian know-it-all Mechanical Turk / HAL / Marvin.

Speaking of the latter, we will have little use for an AGI anyway as such a thing will be way out of our league and we will not be able to use it, as D Adams famously postulated: "Here I am with a brain the size of a planet and they ask me to pick up a piece of paper. Call that job satisfaction? I don't."

> "you cannot unbreak the broken glass"

I really don't like this analogy. You can weld glass back together. Or melt the pieces down and reforge it.

Replace 'glass' with 'vase'.

Analogies are always breaking down but break down faster if people don't just try to see them as analogies rather than the thing itself, the idea was to convey a point and you indicated that you got it perfectly well.
