I feel (hope :-)) that in the future, network bandwidth will be large enough that large, high-power general computation services can be used to offload intense processing tasks from personal devices to work around things like this.

So, if you're on your phone and need to crunch a massive data-set, this gets offloaded to the big-datacruncher-in-the-cloud, and the result sent back to your device.

Bandwidth is only one part of the problem. Latency is another one, and it seems to be insurmountable with the modern network media.

Most people don't run workstation loads, let alone anything remotely resembling "heavy".

The parent comment was talking about "every situation", not "most people".
