I'm currently in a role where I mostly support legacy apps (C# and SQL), try to pass on knowledge and let the "young kids" write new apps in Flutter - which I've been though an introductory course on, so can read it, though I've never written anything but the tutorial app. Some of the issues are interesting (obscure bugs due to rare edge cases), but most of it is repeat problems where the user has done something wrong and needs it reversing. At my age, I've no intention of taking on anything new and will probably stop if the interesting stuff becomes too infrequent or, of course, if I win the lottery! :)
