If it's the case that we are currently a part of a simulation then we can assume those above use are part of a simulation too and eventually we will create a simulation below us and it's turtles all the way down....and up.
That's why the simulation hypothesis is quite likely. We can simulate very simple universes. We will simulate more complex universes as time goes on. And there's nothing to prevent that universes to become really complex, so complex that beings there will become conscious. And it's only matter of time when those beings will simulate another universe.
And, considering that every civilization simulates many universes, there's an exponential growth of universes beginning from the "root" civilization. So there are (or there will be) billions of billions of universes, one inside other, like russian dolls. And possibility of us living in the "root" universe is quite low.
Either that or there's some fundamental nature law preventing us from creating a simulation of conscious intelligent mind. And even if we didn't create that simulation yet, I don't believe that those laws exist. We have billions stars to consume for energy and matter and billions of years to improve our technology. Why don't we create megacomputers with that power potentially at our hands?
That's my take on it as well. We've created fiction that explores the idea (The Matrix is the most obvious recent entry), we've created games which are simulations themselves, and pretty soon we'll be able to create complex, realistic simulations that in turn can create complex, realistic simulations. After all, we've managed to simulate an entire ALU in Minecraft, itself a simulation of life in a blocky world, and there are far more advanced game engines out there.
