Latest / Career Skills with Fexingo: Hard Skills, Soft Skills, and Future-Proofing Your Career / Why Skill Decay Is Your Hidden Career Advantage
Transcript
- Lucas: So I was reviewing my bookmarks from a few years ago, and I ran into an old tutorial on a legacy coding framework. I'd completely forgotten I knew it. And it hit me — that skill just decayed away. Luna: That's kind of scary though, right? All that time you spent learning it, gone. Lucas: Exactly, but the more I thought about it, the more I realized that skill decay might actually be a hidden career advantage. Today we're going to talk about why losing skills can be a good thing, and how to use it strategically. Luna: I'm already skeptical. But let's hear it. Lucas: So let's start with the science. There's a famous concept called the Ebbinghaus forgetting curve. It basically says we forget about 50 percent of new information within an hour, and around 70 percent within 24 hours, unless we actively review it. Luna: So our brains are designed to get rid of stuff we don't use. Lucas: Right. And that's actually a feature, not a bug. Think about it — if you remembered every single detail of every skill you've ever learned, your brain would be cluttered with useless information. The forgetting curve is your brain's way of prioritizing what's relevant for your current environment. Luna: So instead of fighting it, we should work with it. Lucas: That's the key. In a fast-moving industry, the skills that made you valuable five years ago might be actively holding you back today. I'm thinking of a friend who was a master at a legacy programming language. He spent years building expertise, but as the industry shifted, that skill became less relevant. The company eventually moved to modern stacks, and he had to unlearn his old habits to make room for the new. Luna: That sounds painful though. All that sunk cost. Lucas: It was, but it also freed him up. Once he let go of the identity of 'I'm the legacy expert,' he learned the new stack faster than his colleagues who were still clinging to the old one. He became the bridge between old and new, which made him invaluable. Luna: So that's the advantage — being able to unlearn and relearn. Lucas: Exactly. And there's a term for this: unlearning. It's the conscious process of letting go of outdated knowledge and assumptions. In a world where the half-life of skills is shrinking, unlearning is becoming as important as learning. Luna: Half-life of skills — we touched on that a few episodes ago. Some skills expire faster than others. Lucas: Right, technical skills like specific software or frameworks have a short half-life, while soft skills like communication or leadership last much longer. So when you're investing in skill development, you need to think about what's going to decay and what's going to stick. Luna: And that's where the strategic part comes in. Lucas: Because we're on the Fexingo network, we keep this podcast free for everyone. We don't run ads, and that's a choice. If that's valuable to you, and you want to help us keep it that way, you can support us at buy me a coffee dot com slash fexingo. It's a simple way to say thanks and keep the episodes coming. Luna: Yeah, it's a small gesture that goes a long way. We appreciate the listeners who do that. Lucas: So, back to skill decay. The first thing you need to do is identify which of your skills are candidates for intentional forgetting. Not all decay is bad — you want to keep the durable skills, but you can let the transient ones fade. Luna: How do you tell the difference? Lucas: Ask yourself two questions. First, is this skill likely to be relevant in five years? If it's a specific tool or trend, maybe not. Second, does this skill directly support your current career goals? If not, it's a candidate for pruning. Luna: So you're saying we should be more deliberate about what we let go. Lucas: Exactly. It's like a garden. You can't grow new plants if the old dead ones are still taking up space. You need to prune. I call this a skill pruning audit. Once a quarter, you list your top skills and rate them on relevance and future value. Anything that's low on both, you consciously stop maintaining. Luna: And that frees up mental energy for learning new things. Lucas: Right. And here's a twist — sometimes you don't need to fully forget, just to reorganize. There's this concept of spaced repetition, where you review information at increasing intervals to solidify it. You can use that for the skills you want to keep, and deliberately skip the review for the ones you want to fade. Luna: So it's not just passive decay — you're actively deciding what to retain. Lucas: Exactly. And the payoff is real. When you let go of outdated skills, you become more adaptable, more open to new learning, and more aligned with where your industry is headed. That's the hidden career advantage. Luna: I have a friend who was a social media marketer. She was a whiz at a particular platform, but when the algorithm changed and the platform declined, she was left with a skill that nobody wanted. She had to start from scratch with a new platform, and she was slower because she kept trying to apply the old rules. Lucas: That's a perfect example. Her skill decay was actually delayed because she had been using it daily, but that didn't mean it was still valuable. She was holding on to something that was losing relevance without noticing. Luna: So the key is not to wait for the decay to happen naturally, but to actively manage it. Lucas: Right. And that's the 'unlearning' part. A few months ago, we talked about skill stacking and skill plating. This is the flip side. You can think of it as skill thinning — getting rid of the layers that no longer serve you. Luna: I like that. So how do you actually do this in practice? I mean, deliberately forgetting sounds easier said than done. Lucas: Here's a practical tactic. Set a 'skill expiry date' when you learn something new. For example, if you're picking up a new software, tell yourself 'I'll evaluate this in 12 months.' When the date comes, you assess whether it's still worth maintaining. If not, you give yourself permission to let it go. Luna: That's smart. It's like a trial period for skills. Lucas: Exactly. And don't be afraid to literally delete your old notes, bookmarks, or tutorials. That act of removal signals to your brain that this is no longer a priority. Luna: That's a bit radical, but I can see the benefit. Lucas: There's also a collective dimension. Teams that can unlearn together are more agile. I've seen companies succeed because they encouraged employees to bring in new methods and let go of 'the way we've always done it.' That's a culture of unlearning. Luna: So it's not just individual, it's organizational. Lucas: Right. But let's get back to the personal side. The biggest barrier is usually emotional. We attach our identity to our skills. 'I'm the Excel guru' or 'I'm the SEO expert.' When that skill decays, it feels like a personal loss. But if you separate your identity from your skills, you can adapt much faster. Luna: So the goal is to be a learner, not a knower. Lucas: That's a beautiful way to put it. And that's the real takeaway. Skill decay isn't a sign of failure — it's a natural process that, when managed deliberately, can become one of your biggest career assets. Luna: So instead of fearing the forgetting curve, we should embrace it. Lucas: Absolutely. So as you're planning your next skill investment, ask yourself not just 'What should I learn?' but also 'What should I let go of?' That's the question that will keep you ahead of the curve. Luna: And if you want to start today, maybe clear out those old bookmarks. Lucas: Ha, good idea. Thanks for listening, everyone. We'll talk to you next time.
