This blog post is nonsensical and the arbitray time boxes aren't realistic. Not all development cycles or features require legal input and I would hazard most don't, even in Big Tech. Documentation takes seconds to generate. Same as tests.

Feature development could take minutes to hours depending on how you iterate it. These days, all we do now is just think of a feature and add it within an hour using AI. We have a process that is a year old now that is fixing bugs that would have taken us hours or days and it spits out a fix in about 10-15 minutes that is 95% accurate. 5% is garbage, but 24 months ago, 95% of it was garbage so the progress is staggering. The longest pole is code review which is all human, but that will all be automated soon.

Not everything will be much faster, but most processes will be 1-3 orders of magnitude faster. To ignore this or find excuses why LLMs/AI won't speed things up or remove the need for large swathes of humans is delusional and cope-ism.

In my world automotive/mechanical engineering we are also observing how much AI can help you build a mental model, fetch unstructured data and help shape your understanding of the system. Onboarding new engg. figuring out what is what in the system. It could have taken hours before to fetch right info, now we are able to do this in seconds.
