and their consequences when developing his or her own applications?

Was it ethical to develop software in the 1970s using only two digits to represent

the year (such as using 76 to represent the year 1976), ignoring the fact

that the software would be flawed as the turn of the century approached? Is

it ethical today to use only three digits to represent the year (such as 982 for

1982 and 015 for 2015)? What about using only four digits?
