A. The Enterprise is loaded with people, loads of people, doing jobs that should be automated.--Except it is automated.

This Side of Paradise Kirk is stranded in orbit while everyone is having their love-in, because he cannot run the ship himself. You need a crew to run a TOS Starship.
People are necessary in later Trek to fix systems when they break down. The transporter is always breaking. The engines are always out of whack. The plasma conduits are always flurgibbiting when they should be flurgabitting.
TNG era starships, however, have enough processing power to create sentient life. The ship, given the ability to monitor and repair its own systems would be better off. The ship is smarter than the monkeys "running" it. Give it robots, or holo-agents (a la the holo-doc on Voyager who was free to mover wherever he wished) to do the manual repairs, and why do you need people?
1. The TOS Enterprise has "phaser crews." --Military redundancy.
Bad redundancy. There are so many other and better ways to build redundancy into the system which do not involve a crew of people to have a special "button pushing" job. This is like pulling a horse trailer behind your car as redundancy (in case of motor failure: ride horse).
The Captain calls out an order. This order has to be verbalized. That order is transmitted from the bridge to a special room on the ship. In this room another person has to hear the order, understand it, and then physically push a button.
Not the best way to engage in combat for ships that travel faster than light.
And note - at the end of the line on Star Trek, the muggle in the Red Shirt is still pushing a button somewhere in the bowels of this ship.
The circuitry and systems still have to be working on the ship for the Red Shirt to do his job (pushing a button in a phaser room).
It's not like you can get out and row if the engines break, or put up a sail and hope for wind. Your life always depends on the machines working on Trek. And so long as they're working, let them work as best they can (get the people out of the way).
If you want to meet people, go out and meet people. If FTL wasn't possible then probes would make sense.
Send probes as your emissaries first. If it is safe you send people in next. First observation and first contact should be done by a probe.
How can the computer serve as security guards to be killed by the villain of the week?
Which is why Trek is backward looking. It puts people in old-fashioned situations to be killed. I am not saying that Steampunk or Atompunk (give it a name) doesn't make for good drama, but the sort of drama it is purposeful looks backward to create easy tension.
--Or they could train for when they are needed in emergencies.
But they don't. They're all scrambling for career advancement and getting yelled at by superior officers. They die anonymously. They're fodder for the hunches of their superiors. When equipment fails they pay the price.
All of whom were either doing jobs that they actually liked or where trying to prove themselves to earn promotions to the jobs they wanted.
No one wants to be the Red Shirt. Everyone wants to be the Captain. When Picard lived an alternate reality as a muggle, he was miserable. And most people on the Enterprise are muggles.
Not only are their jobs unnecessary (which means that they're just playing out a hierarchical social drama), their jobs are also dangerous, and most people are stuck with grunt work. For every Riker there are three hundred Barclays. For every Kirk there are three hundred Finney's.
I though the computer was everywhere but that it helped to have visual interfaces, a picture's worth a thousand words after all.
The interface should be in their brains. They should be directly interacting with the computer.
Here's the thing, even if that happens, would we allow it?
LOL, how many times a day do people check their facebook status on their smartphones?
People want their smartphones (the new laptop) to be portable, powerful, ergonomic, and convenient. This means small devices which are, basically, an extension of their will. The terminus of all the technological yearning for connecting our will with information processing and control is to connect our technology, as closely as possible, with our will. And this means implants.
Barring a need for something like a Cochlear implant or something similar, how many people would let a computer be implanted in their brain? Or allow the same to be done to their children? I'll take computer interfaces please.
And I passed on tattoos, piercings, and body mods - the kids, however, love these things.I passed on cell phones for a long time, but they're convenient and powerful.
My grandmother passed on microwave ovens and laundry dryers until late in life -- and then she loved them. She couldn't stop raving about how marvelous it was to warm coffee so quickly and how nice clothes turned out.
My job basically requires me to have a computer and a cell phone and to accept job payment in the form of electronic direct deposit. If you want a discount at a store, you basically have to agree to use a loyalty card (given our economy, this can be coercive). My point? Implants won't be optional in the future. You'll either have to be Amish or adapt.
The Computer can stay out of my head, thank you very much.
Your head is a computer.
Why do I care what a copy of my mind does?
Anyone about to step into a transporter should ask, what do I care what a copy of my body does on the other side?
Would you use the transporter?
