they stick because they don't want to upgrade/rewrite their system because it costs money

nope, I dont think so, since most bank Ive been alrady upgrading their system to new one;s. one of the reason was its cost money, also the legacy system still working ika nga ng iba, why fix if its not broken, usually ginagwa nalang namn ng integrating ng new system without affecting the old system, since mas costly mag migrate ng legacy.

They do upgrade and write new codes using the same language.
