I see engineering, not software, but the other technical areas that have the biggest threat. High paid, knowledge based fields, but not reliant on interpersonal communication. Secretarial and customer support less so, they aren't terribly high paid and anything that relies on interacting with people is going to meet a lot of pushback. US based call centers is already a big selling point for a lot of companies and chat bots have been around for years in customer support and people hate them and there's a long way to go to change that perception.
