The problem isn't the series, the problem is that people have not been paying attention to the environment this world operates under. As pointed out, we seen that the ninja world depending on the village and resources have created some form of modern tech already. We have radios, video cameras, and computers. Then look at the hidden rain's infrastructure. Look at Sora-ku.

The problem is that you have a fractious world made worse by chakra. Technology develops when there is something people want to do or make easier. The problem is that with chakra and jutsu, the to go to method is to just make a jutsu that covers that need. Despite that ironic handicap, a technological revolution was always under the surface.

I am not shocked that Kumogakure had a chakra canon. At least with the Fourth Raikage, the policy has always been to push forward with military build up & development no matter what armistice treaty they sign.

Kirigakure's problem is that it is racked by civil war and a high defection rate of its shinobi, and down right genocidal tendencies towards anybody with a KKG until the Fifth's era.

Suna has a population & resource problem being that most of their country is a desert with gold pretty much being their main if not only non-shinobi contribution to the international trade/economy sphere.

Iwa has the issue of just bad at organizing its forces and resources by having a high number of shinobi but 2/5 economy rating. It is bad enough that to keep up, it had to like Suna, use mercenary groups to maintain their standing in the shinobi world because there isn't enough properly trained shinobi around.

Kohona has or had the best of everything, but the issue is that it is a constant target for invasion by powerful shinobi and groups starting with the Fourth's era, and that has crippled it until it got itself together after the Fourth Shinobi War though it had periods of peace like during most of the Third's second tenure when you ignore the Uchiha Masscre, but that is a case of bad domestic policy made worse by instigators like Danzo.

With the Five Great Shinobi Countries/Villages not constantly at each other's throats, and the Shinobi Union helping to iron out the economic and disparity issues among its members, you got a them sharing resources and to some level knowledge that has led to a tech boom. Of course each village is keeping some secrets with the ninja tools and robotic development meant to be a Kohona secret project, but at the least other countries aren't hiring assassins against each other this time around because at some point these projects will be made known to the public to some point in the future.

TDLR: Prior to the fourth war, everyone was too busy killing each other with jutsu and dealing with economy woes to sustain a tech boom, and post fourth war, with cooperation & peace genuinely on the mind, the scientific potential of the shinobi world is unleashed.
