Bostrom's argument is based on rather implausible and far-fetched assumptions, e.g. speculation about what advanced civilizations would do or not. There are more interesting variants of the simulation argument and many types of simulations could be detectable. To give an example of what makes the question principally interesting, one could claim that storing an infinite amount of information within a finite amount of space violates the laws of thermodynamics and is therefore not physically possible. Hence, real numbers don't exist and the universe is discrete. If it is also finite, then you can simulate it on a computer. What I'm saying is that even though the question whether we are in a simulation is mostly speculation, there are some principally interesting corollaries about it, and some of them are physically meaningful in the sense that they can be confirmed or falsified by experiments at least in principle.
