Okay what we're saying is slightly different, you mean to reach a certain bar. I kind of agree to that
Through the marginal improvement is still pretty high to knowing how the tools work and how to use them more effectively, in a way that people that spend time with the tools will be _more_ effective
The point is the comparison between the levels of tech. Your accountant is constant, the tools they use is variable.
Interpreting the OPs point as "absolute zero skill" is against HN rules to interpret comments reasonably. You guys are trying to find the most stupid angle possible for the sake of an "argument". I hate this antagonistic debate culture so much.
Yes?
Try abacus, slide rules or mechanical calculating machines vs electronic calculators.
Or ancient vs modern computers and software. They didn't even have "end-users" like we understand them now, every computer user was a specialist.
Programming.
Writing. Quill vs. ballpen, but also alphabets vs what you had to write before.
Photography, more than one big jump in usability. Film cameras, projectors/screens.
Transportation: From navigation to piloting aircraft or cars. Originally you had to be a part-time mechanic.
Many advanced (i.e. more complex than e.g. a hammer) tools in manufacturing or at home.
