Sure.Personally I treat it as a golem. It's an illusion, not a "real" creature and as such has little or nor motivation or personality of it's own. While it follows your commands, it will follow them literally. It's not completely unintelligent because that would be annoying, but it doesn't need to eat, sleep or defecate.
It doesn't act on it's own initiative or have any motivation, much less the desire to converse with other individuals or read a book. It can remember simple things, but it's never going to really comprehend any deeper meaning although it could probably parrot what it heard if asked.
Sure.
While that answers the OPs question, it does not even attempt to address the real balance issue imposed by the spell.
That is why I prefer a different approach to the OPs issue.
To me it's both more interesting AND better balance if the Simulacrum is given independent will (much like an Awakened animal).
Not only does this present an interesting role-play challenge - "what would you do if one day you realized you were created, and consisted of magical ice?"
It also gives the DM all the power he or she needs to shut down abuse with "I won't do it".
I definitely consider "let's cast this spell to create a disposable copy of myself that I can use as a pawn in dangerous situations, and/or save a truckload of spell slots" to be abuse here.
I realize that's pretty much what the spell was intended to do, so I can't argue if you simply keep the spell as is.
But in my game that's pretty much the only option if you want to avoid me banning the spell completely. Yes, it's that ill-thought-through and overpowered.
Keeping the spell as-is basically negates every check and restriction on high-level spellcasters that 5E added. (Especially thinking of casting the spell through Wish here.)
If y'all are fine with that, by all means keep it. I'm not.
You ever see the movie Memento?
Yeah, that. Good luck with the tattoos.
Sure.I agree that the spell is probably overly-powerful, especially if it just becomes a disposable version of the PC. I considered just banning it or setting up some other limitation such as only used so many times per year, etc. I decided on the golem approach because they follow orders very literally, have no sense of self-preservation, and won't do anything on their own. Told to watch the back, they will watch the BBEG walk up behind the group to get into position because they were not told what to do if an enemy appeared. Complex instructions during combat are limited, typically to half a dozen words or less. It's a friendly robot that won't pass close inspection or interaction as a real person.
That at least partly addresses the issue without completely nerfing or banning the spell which was my other option. As far as being overpowered, I guess that's in the eye of the beholder. I adjust difficulty level based on the capability of the group, including spells like this.
Sure.
I just happen to think making the simulacrum unreliably stupid isn't ultimately very interesting.
But you're right that it does adress the issue. Guess I didn't read enough into your use of "it's a golem"
