People would be really surprised how much of the critical infrastructure of this country in government and enterprise runs on technologies around half a century old. This is nothing new. The IRS still uses millions of lines of COBOL to process our tax returns, the VA uses millions of lines of MUMPS (M) to store and process health and benefits records, and the list goes on and on. It&#x27;s not going anywhere soon, either.<p>People skilled in these legacy languages and technology stacks are also amongst the highest paid and most in-demand in the country, at least here on the east coast in places like New York and DC.
