2) If robots do replace all jobs, the "money" comes from sale of goods just the same. Half the workforce are working and doing the work of the other half - the robots produce the goods / services, and the humans lounge at home.
And just who is going to give money to the humans lounging at home with which they will pay for housing, food, clothing, transportation, goods and services? How much money will they be given? Or is this "home" you speak of just going to be a tent in Hooverville?
3) The result of the above is that food and goods become so cheap and plentiful that the concept of "buying" them will seem old hat.
The economic system is one where all goods and services have to be paid for at some level. Even subsidized services like public transportation and health care require some level of payment. Are you suggesting that the long-term unemployed will be government subsidized sufficiently to have an apartment to live in, with Internet, streaming electronic entertainment, beer in the fridge ("free as in beer") and an endless supply of junk food?
5) Who cares? If you have no job and no money but food is so cheap that going an oiling a robot once a month pays for everything - wow... perfect life.
Even if food, goods and housing are amazingly cheap, if you have no money to pay for them, then they are still too expensive for you.
Back in the 1960's, there was a TV show called "The 21st Century", which was narrated by Walter Cronkite. He kept going on about how much more leisure time people would have in the 21st century. What the futurists of the day forgot to consider was that if you put everyone out of a job, nobody is going to have money to spend, and thus there would be no market to sell to.
You can have truly great sound for an affordable amount of money, but you can have great sound with pre-packaged junk like what you get from Cambridge Soundworks or most anything else you connect to your laptop or iPhone. Affordable great sound is had by purchasing speaker drivers from Madisound and building your own enclosures. It's had by building your own tube amps from tubes4hifi.com. It's had simply by caring about what you're hearing and using a little common sense.
I love my Quad 57 ESLs ~ https://en.wikipedia.org/wiki/...
I used to run full-range electrostatic loudspeakers, but have since moved on to the home brew designs of Siegfried Linkwitz. Very, very affordable major hi-end. You can't buy better sound than his home brew designs.
Insanely great sound can be had for a reasonable amount of money if you're willing to DIY. Check out the loudspeaker designs of Siegfriend Linkwitz at
It's not cheap, but it sounds every bit as good as gear costing 30 - 100 times as much depending on which design you build. The LXmini can be built for less than $1k and within it's limitations, sounds as wonderful as anything AT ANY PRICE.
There was a time when the experience of live musicians is what defined what the musical experience was, and so good audio was an attempt to recreate that experience at home. What's sad is that today music is consumed rather than seen as the product of live musicians, so good quality audio just isn't valued much anymore.
An authority is a person who can tell you more about something than you really care to know.
