However 99% of businesses will not be able to effectively handle security reports in reasonable time. They did not need that level of competence or funding until now, and therefore they did not acquire it. Most companies that use locks don’t employ locksmiths.
Looking another way - the entire economy got suddenly hit with entire pile of technical/ security debt it has accumulated over 50 years, and only has one year to deal with it. No amount of diagnostic will fix this, this is economically infeasible.
One thing that is feasible is a government bailout for technical debt. All the engineers that were freed up from AI-induced restructuring should be employed to pay down technical debt across the entire economy. Simply updating all software to use latest libraries is a great start. Using AI to diagnose, repair, re-deploy all old software. Using AI to rewrite all old software that cannot be recompiled.
