The purgatory is a perfectly self-contained 10-acre plot of land that you create limited mostly by your imagination, but you’re cut off from the world and other people.
The internet connection is stable, but you lack a physical body and cannot upgrade the machine hosting you - your hardware will become out of date fairly quickly.
You say the hardware will be outdated fairly quickly and I’m not sure what you mean by that. If it’s strong enough to completely simulate a human consciousness then it’s probably better than anything we’ll build in the next 20 years. Or is there like a magic usb stick connected to it that allows me to interface with the computer? Well, either way I choose the computer. I can just rent a server if I want to do more computationally intensive stuff.
