You're building up technical debt. The concept here is that you can spend $N every year on updating and refreshing the technology you are using, or you can depreciate your asset by $M per year if you don't, and you need to assess whether $N exceeds $M.

The depreciation you apply depends on whether you're doing any ongoing development. If you are, then you should factor in that moving to new technology will reduce those development costs.

If you want you can also factor in risk (how exposed are you to some major discontinuity that stops the whole thing working, e.g. a security vulnerability), support costs (is there anyone who still knows this stuff?), and staff retention (can you find good people who are prepared to work with old technology).

So it's not a question of like or dislike, fun or no fun, it's a question of economics, of minimising the lifetime costs of your system. Of course, the calculations will come out differently for different projects.
