Sorry just my 2 cents but the way i see it is CodeIgniter is an awesome framework and even though ive only this year started using frameworks, ive tried laravel mainly because the cool kids were doing it but after a while (and discovering CodeIgniter) ive gone to using CI for everything. Mainly due to its simplicity and low footprint. Everything you need is there and if you need more github has the answer with a script which is easily integrated.
In my opinion i think that Its not how do we get Ci to be the best is how long before people realise its potential.
Not that much of my rant compares to many of yours but as a developer in training and starting from scratch having to look for a suitable framework to start off with i just find Ci the best one of the lot.
Also the community is absolutely brilliant with CI.
