You will be happy to know that in India at least, the big CBS (finacle) is in poorly written Java instead.

Made on least cost basis, protected by a moat a central bank wide, and maintained by 10k /year engineers, it is truly a marvel that our country's banks even run.

The company i intern at has built its entire business off moving as much functionality outside finacle. A small modification of changing a label's font, can cost a full 100-150 usd.

Never mind adding in custom features and the like, which costs a pretty penny if you use infy.
