They said "A" good dev uses an ide, and a snappy 'in 2020' retort. It's plainly clear their intention is to imply only good devs use ide's in the modern era.

No, that's not how simple if statements work. I don't know what else I can say.

If I say "A good CPU has more than two cores in 2020." then I'm just saying it's a requirement, not sufficient all by itself. I'm not calling a twelve-year-old phenom X3 a good CPU. The "in 2020" is just to emphasize that anyone failing this standard is falling behind the times.
