Nobody can predict the future, of course, but I personally believe this pattern will hold. A decade from now, the idea of a consumer being able to purchase a personal device with more than 8GB of RAM will be a thing of the past, all significant compute will be done in the cloud using the massive amounts of hardware being hoarded by corporations as we speak.
The only way this is remotely possible is if the copyright cartels get their way and make it illegal to have unlicensed local compute. Assuming that doesn't happen, I'd gladly bet a large amount that computing will be much more affordable 10 years from now.
