Here's my take on the future here: With AI, code is disposable. The only reason to "maintain" instead of rebuild before was sunk cost and the time it used to take to build something. But AI can cut that cost to a fraction and make it more worth your time to just rebuild (and this will only get more true over time). If it gets too broken, throw the codebase away and make a new one. No more ten-year-old codebases that have been "maintained" to the point of obsolescence! It's a new paradigm.
