This industry is the very definition of career do-over. Every 5 years or so we change our activities. No one writes code or design like 20 years ago. With a career of 50 years, we are all doomed to have to change. Adapt over time. Don't just jump. Take on new responsibilities. You will find experience crosses many fields. It's a lot about domain knowledge (e.g. financial industry) and we carry a lot of stuff over with us. Never undersell yourself, experience is king. Always be keen on learning, asking questions to younger self. Cross pollinate, experiment and be curious. Too many old devs just corner themselves. They shouldn't, they have a gezillion experiences and it always comes down to a race condition ;)
