Think about it - if your parents' jobs were permanently eliminated right now, what are the odds that they can successfully shift into programming?
Do they have the funds to go back to college?
And - apologies for making some assumptions about your parents - how do you think the interview will fare for someone in their 40s or 50s (or 60s?) who just finished learning basic programming and is ready for an entry-level position?
Be honest about that one - we work in the same industry - we know exactly how it treats middle-aged people.
So yeah, we've created new jobs at the same time others are being eliminated. People are taking these new jobs - but it's a mistake to think that these two groups are largely the same people, they are most emphatically not.
So the question is: if your parents' jobs were eliminated permanently, what do they do for the remainder of their lives?
