Read up on the whole no-code thing. Zapier (along with the API-based services it plugs into) has essentially enabled an entire philosophy around startups that does not require the use of a code editor.
I think that we're going to see a rejection of no-code in a few years. Whatever the new word for visual programming is, it comes in cycles and the visual programming tools adopt more scripting integration and then we come back full circle.
This may be a failing of those who develop visual programming interfaces, honestly. These tools are often built for non-technical users and to build in more scripting integration harms the original value proposition … which then leads to the next generation of visual programming tools.
You can place the origin at any offset in a circle and rotate 360 degrees to get back to it. One paradigm adopts features from the other to better express complexity or lack thereof, and the cycle transitions when someone decides "there's a simpler way to do this, I shouldn't need to hold all this in my head."
And at the end of the day these tools are competing with Excel, which supports both visual and textual programming for the same reasons.
Basically, the idea is that you can build a full-on app without having to dip into code, allowing you to develop an idea and prove it works before committing to it with more in-depth development.
