How hard is it to do this? Have we mapped out the brain to figure out which signals to send where to make us believe we're having a fully realistic sensory experience which are infact nothing more than machine outputs?

not even close to getting close.

we barely know how our bodies work. bioscience/medicine is considered the last of the low hanging fruit in regards to scientific progress.
our hardware advancement has also started to stall. moore's law isn't holding up so good nowadays .

So we've hit a sort of wall in terms of progression due to the lack of new resources? Seems to me like we should usher in a new age of exploration and discovery. One where we look towards space. One where we look towards the ocean. And perhaps, one where we look towards... aborted fetuses for resources assuming that's ethical.

There isn't even agreement on how single neurons actually work (Is neural signal processing done via surface potentials only, or is there a whole order of magnitude more computation done within neuronal microtubles themselves?).
The "hard problem" isn't even close to being understood and we have no idea for sure what processes are involved in the phenomena of coherent qualia.
There's also disagreement if all qualia even arise solely in the brain, or if the rest of the CNS plays a role, for example the qualia of "touching" something probably arises both in the nerves that send the signal to the brain and the brain itself.

It's obviously the former. Neurons are neurons, not microprocessors.

Holy shit get this guy a fields medal
I think we're pretty close

there's experimental evidence showing that spiking occurs before the surface potential could fully pass around a neuron, in fact it seems to happen pre-emptvely and the only known theory to explain that is tubulin channeling ions, and said tubulin can be deterministically gated within the neuron. This alone wouldn't imply signal processing, however tubulin getting tangled is one of effects of Alzheimer's, when that does happen the synchronous spiking patterns of surface potentials on both sides of a neuron no longer seem to occur correctly.
