Well, besides the economic fallacy loaded in those kinds of statements, I just want to address the 'taking away jobs' aspect. To do this, I will give but one simple recent advent, Cyborg Insects.
What's that? Well, details can be found here. In short, it's a lot safer, smarter and more humane to let technology do the dirty work in cases where it's simply too dangerous or risky to send people. Would you want your son or daughter to be sent into a hell pit if you knew there was viable technology available that can do the job? Doubtful.
And this is but one recent example of technology displacing people doing dangerous work. Technology (robots) can do mining. Technology can and does manage heavy manufacturing. In fact, were it not for the advent of some key technologies, we'd still basically be dependent on slave labor to accomplish some of the major construction tasks we do today.
Yes, technical advancement displaces human labor. GOOD! It's about time people wake up to the fact that we invent these tools to help us, and part of that process is developing tools that FREE us from the drudgery of monotonous and dangerous work, liberating us to pursue our personal passions, and more intellectual avenues.
Technology is more efficient, faster, doesn't need breaks, yadda, yadda. I'm sure you've heard all that before. Well, maybe you've heard that because it's true.
Now maybe it's time to reflect on what it means to work, what work is supposed to accomplish, and how mankind is supposed to live within a paradigm that renders human labor more and more obsolete.
Here's a hint: analyzing human labor for income is a start.
