You meant "expand massively" i think. Did all the programmers manually making machine code get fired and the job of programmer disappear when compilers were invented and totally replaced these jobs? No, it just changed to use the new tool.

There wont be any unprecedented mass layoffs, despite what the jaded STEM-hating twitter crowd wants. Companies will simply make their programmers use these tools to increase the amount of produce per employee, and make software that would have been otherwise financially impossible to be made. Because the competition will do so too to get ahead.
