Future perfect continuous. In a first conditional structure. If I'm still doing the podcast, it means that I'll have been doing it for 15 years. And then future perfect continuous passive. This is you speaking because you're a listener. You might just be listening because you're probably on a bus or in bed or something like that. But if Luke is still doing this in five years time and I'm still listening, then he will have been doing this for 10 years. That's how longLuke has been doing his English podcast. He says: "I love expanding my work online in some way". Sounds a bit like there's a ghost word in their love.
