Then you need to understand that travel is already trivial - how is it not? You press J and that's it. So an AP doesn't make an already trivial thing any more trivial but it cuts down on the pointless J pressing.
You don't only click "j" when exploring or travelling, nontheless, it is the demand in time that matters. AP does in fact eliminate this as now I can just leave the computer playing itself while going to school. Essentially, your idea transforms travelling to waiting.
The other thing is that going to Colonia is not an acheivement. Nobody can "get a sense of scale" to the galaxy either - it's impossible to conceptualise the size for the human brain.
The only way to conceptualize size is by the time it takes you to get somewhere. Obviously ED doesn't inform you how many trillions of Kms you are away from something but it conpensates via the time it takes to travel through it.
The only Endurance needed is in your head. To basically get to another empty point in space with a slightly different star background isn't a thing. What most people won't do is sit there for hours on end to get to a part of the galaxy which is exactly the same as every other part of the galaxy because RNG ensures you see the same stuff everywhere.
Factually wrong, there are in fact places where certain stars are more common.
You say an AP makes there "no point in getting there" well no - press J over and over is as pointless.
Its time, not the J key that matters.
There is literally no point going anywhere in ED as it's all the same everywhere due to RNG. An AP makes no difference and if the very fact of pressing J is all there is to making journey's, then I don't know what to say about that but it's not fun at all.
Now, if you think there's nothing special beyond the bubble then why would you even want to exit it?
There's also another point in that you don't have to use it so why does it concern you? Could you imagine the same argument for the docking computer? It trivialises docking! Yes it does but so what? If anything, there's more of an argument to remove the DC and add AP because at least docking is actually flying the ship.
Not at all, you know why? Because it doesn't take time.
There's also AP's already out there like this one. Look on youtube for "Elite Dangerous Autopilot" there's a couple I found, one here...
So, then there's no point to continue.
In a manner that is sheer, unadulterated drudgery for zero benefit to the player?
Friend, that isn't gameplay. That's a job. I know of assembly line jobs you can get paid for that are more stimulating.
Is AP gameplay? Is allowing a player to progress by just sitting down and reading a book gameplay?
