In the "iceberg" of boring company systems I see working day to day I actually think delivery of production software has been slowed down. The cost of "writing" code went down a bit, while validation costs positively exploded.

There are definitely more apps developed these days but I haven't seen anything much vibe coded which actually seems to have staying power. Everything is prototype quality.

Now you can make a prototype without understanding what's going on internally or why the prototype wasn't good enough!
