He hasn't been in the industry long enough to see that most of the pillars of software engineering are built on top of massive tech debt.
When I say tech debt I mean design flaws created by designer who simply could not anticipate the future. I'm not talking about bugs, mistakes or intentional shortcuts.
Whether jenkins is "tech debt" is a different topic. But whether Jenkins is here to stay past 2025 has nothing to do with how well it's designed.
