There is no invention (that i can imagine) i would look forward to if Mind Upload VR was real.
That would mean stagnation, but progress is only good if it reduces suffering. And i just can not see how making faster computers and learning physics can reduce suffering if there is Mind Upload VR, where all pain is optional.

As long as the VR is more like a Matrix where the body still ages and dies, of course i would want research to continue so death does not rip me from my awesome virtual life before i have played it trough. Maybe even multiple times.
I agree that progress will most likely slow down once Matrix VR is real because why waste your precious years lerning physics and biology when there is affordable VR?
Once Mind Upload VR is there i can actually see science progressing much faster, because if you have a processor that can simulate one conciousness and be loaded 10%, you can either put 9 more people on it, or you could speed up time 10x, so the mind that is researching new technology will experience 10x more time than real time and be done with research much faster.
Or you could store yourself on disk and wait 1000 years to have science catch up.
