The trades are pretty democratized as it is. Every service company I use with is hiring at all levels. Training is available. If you have to get a certificate before you start, that's a barrier to entry, but a nearby community college is likely to have classes.
The real barrier is it's a hard job, and other work is more tempting for a lot of folks.
Tech for trades either looks like a centralized dispatch service that takes 10-30% of the fees and results in a new person showing up for every job (no thanks! Once I find a plumber I like, for non emergency use, I prefer to work with the same one) or maybe something per company that helps organize appointments, scheduling, billing, and notifications about arrival times. This may reduce / eliminate office managers / answering services for busy firms, and could help improve communications for owners that have no employees; but I think it already exists.
There's also potential for planning / drawing / information tools. Augmented reality and stuff. Knowing and recording where the pipes and things are. Sourcing materials. Things like that.
