Like anything else, it's worth what people are willing to pay for it. If you can find the people willing to shell out the coin for the expensive fancy control systems, the enterprise grade networks they make them require, and the maintenance contracts that go with them because they need kid gloves, and remote support to fix all the bugs and glitches, more power to you.

If you would rather sell something simple, that serves it's purpose well, makes the clients happy, doesn't break, doesn't fill your schedule with service calls, and gets you referrals, congratulations. 👍

There are plenty of companies out there willing to serve both ends of that spectrum. Pick which side you are most comfortable on and stay in your lane.
