I visualize a time when we will be to robots what dogs are to humans, and I'm rooting for the machines.
We often attribute 'understanding' and other cognitive predicates by metaphor and analogy to cars, adding machines, and other artifacts, but nothing is proved by such attributions.
By working hard we could make an average of about $5 a week. We would have made more but had to provide our own machines, which cost us $45, we paying for them on the installment plan. We paid $5 down and $1 a month after that.
I learned the business in about two months, and then made as much as the others, and was consequently doing quite well when the factory burned down, destroying all our machines - 150 of them. This was very hard on the girls who had paid for their machines.

When ATM machines came out and people were prosecuted for robbing ATM machines, I don't think anybody thought the banks were against technology because they didn't want their ATM machines lifted.
C was already implemented on several quite different machines and OSs, Unix was already being distributed on the PDP-11, but the portability of the whole system was new.
There were sometimes from forty to sixty English machines, but unfortunately the Germans were often in the minority. With them quality was more important than quantity.
For the first time, individual hackers could afford to have home machines comparable in power and storage capacity to the minicomputers of ten years earlier - Unix engines capable of supporting a full development environment and talking to the Internet.
The workstation-class machines built by Sun and others opened up new worlds for hackers.
Thompson and Ritchie were among the first to realize that hardware and compiler technology had become good enough that an entire operating system could be written in C, and by 1978 the whole environment had been successfully ported to several machines of different types.
If Unix could present the same face, the same capabilities, on machines of many different types, it could serve as a common software environment for all of them.
No more than these machines need the mathematician know what he does.
