Your examples are productivity boosters that don't threaten job security. A human has to provide inputs to the compiler, the spreadsheet, and the tractor.

The tractor, or more generally farm automation, was maybe the biggest single destruction of jobs in human history. In 1800 about 65% of people worked in agriculture, now it's about 1%. Even if AI eliminated every single computer programmers' job it would be a drop in the bucket compared to how many jobs farm automation destroyed.
