Yeah, this seems like a pretty dumb conclusion. I expect that as far back as you look, people always took advantage of tools that save them time. But then they always also spent a fair amount of that time (that they could have been working), just maintaining/fixing/making their tools. I think the truth is that computers are very useful tools, but the maintenance and troubleshooting can be quite time consuming.
I will continue using computers though.
Keep fighting the good fight.
