How did CodeIgniter run out of steam?

@balramdau,

I actually disagree with you when you say Codeigniter has been mostly phased out. Codeigniter did go through a rough patch but it still stayed true to it's principles of lightweight and fast. It's still being widely used and it still is in the conversation of top PHP frameworks (https://kinsta.com/blog/php-frameworks/ ). It just released a 4.x version utilizing current PHP PSRs and there is no telling what the future still holds.
