[General] Why is there highly advanced firepower for small arms in various universes but no equally advanced targeting/guidance system?

I get shooting is a strong discipline; it is useful no doubt about it. I just don't get why from a design point of view there are sophisticated weapons that shoot lasers, plasma, and every other manner of projectile, but they rely purely on a human being to aim it? I'm not saying full on self guided weapons, I just mean more target assisted weapon.

Feel free to use whatever subject you feel comfortable elaborating with.

Because there will always exist the technology to hijack those guidance systems and turn them on the users or civilians.  Not only that, but the threat of sabotage makes something targetable all the more dangerous.  But, most important, the more complex the technology, the easier it is to simply just not fucking work or be countered.

Think about it: how many times have we seen in our collections of cross-universe historical programs a robot that turns sentient?  How about a weapon that fizzles out because of sabotage?  What about weapons that backfire?  Or technology that's hacked and nobody finds out about it until the last second?

Better yet, just take a look at 2014 Earth Prime.  Our washers from 1950 are going strong while washers from 2010 are failing every day.  We got to the moon in 1969 but the Chinese can't even get a successful moon operation going entirely in 2014.  As we try to cram more and more complexity into every-day technologies, we invite issues.  Older aeroplanes are immune to EMPs, but newer ones will fall out of the sky with a single easy pulse.  Older cell phones were bricks that worked fine, newer cell phones break at the drop of a hat and a software malfunction in a single app can make the whole phone lock up.

But let's take a look at the Enterprise, NCC-1701.  While the Federation had the technology available for more state of the art luxuries aboard the ship, the Romulan War made them paranoid enough to intentionally dumb down some of the ship's work stations.  While they still did all of the intended functionality, the bells and whistles we associated with the alternate NCC-1701 were not present.

When your gun jams, you can have a crew fix it or pull out another or have someone take over while you get your shit fixed.  If you only have one gun and something inside just breaks or gets disabled by an enemy, and every other soldier you are partnered with is fucked too, there's no alternative.

Besides, if you think there's no target-assist on many weapons you must not be referring to targeting systems.
