I worked in industrial automation for a few years and most of the software there is terribly outdated. It's definitely ripe for disruption. There are "firm tech" business ideas that involve building better sensing and control software for hard tech industries. Given the low cost of sensors and networking these days it's not prohibitively expensive.
I think making a hard tech product for consumers is still very hard, and those who succeed should be commended. People wanting to dip their toes in the water might consider things like building a factory management portal like Splunk that aggregates sensor data, or something that involves sensing and reporting rather than actuation. Actuation can be dangerous and therefore legally risky.
