I heard this false justification already in 2007, in spite of many customers asking for it.

Incidentaly, smaller competitors solved this issue decades ago, while the big cloud decided it is more convenient never to implement it.

Big cloud didn't want to rewrite its billing systems from scratch to please its smallest customers.

With AI it should take like a weekend.

I think they already tried rewriting billing with AI. Very smartly they only tried rewriting the estimator first. This post is about the outcome of it.
