Do you think its enterprise software? or the team? I work on a product ( https://www.mywildeye.com/ ) but we do a lot of back end enterprisey type stuff to manage our logistics / manufacturing as well. We are a small dev team with a lot of latitude to make decisions. For us, AI allows a dev to deal with a lot more things. We also churn out internal tools like crazy. Our Hardware, Firmware, Accounts, and Support people are all creating tools. Our CEO (former developer) is also getting back to making things, we recently released a free ios app https://epicfields.app/ so farmers can monitor water demand using free satellite data.

Very Large Enterprise is very hard to change, or rewrite, especially old systems. Our company mostly sells contracts to large corporations / government institutions (1500+ employees), with an insane amount of transactions, functionality, etc. Even with the latest models you cannot automate everything, the world is far too complex, and there is quite a bit of pushback when anything changes.

In order to keep some of these extremely large contracts (using Samsung as an example here) for example, we had to revert certain changes that were global but now we have a "Samsung version" because we want to maintain a large presence in Asia and Samsung leaving would be a huge blow.

At this scale, code isn't even the bottleneck, it's customer wants, politics, etc.
