Software engineers spend every day trying to automate away their jobs, and it's hardly a conservative field.
If it were easier to use a visual interface than code, then devs would figure it out and we'd all start doing it.
The "no code" revolution is probably more accurately the Microsoft Access replacement for our generation. Sleeker, cooler, more professional. But like Access, you have to replace it with real software when it starts getting complex.
I think this is just it: text has a higher information density than (say) visual programming tools. At some point you quickly reach an amount of threshold of complexity where you either need to:
1. Hide parts of the program (e.g. hidden cells on a spreadsheet; attributes of nodes in a visual programming environment)
2. Switch to text for the higher information density.
I think the burden of #1 quickly surpasses the burden of learning to work with #2.
