Yes, because eventually technology will kill us all. Look at the scamdemic. Yeah, it was a bunch of bullshit overreaction, but the virus was created by scientists Ralph Baric and Shi Shengli as part of "gain of function" shit for the sake of science. What do you think is going to happen when anyone equipped with $10,000 lab equipment can make up their own virus in their basement? Because that's the future we're headed for.
Or transhumanist technologies which will let people splice themselves with animals to make up new species. That's what furries want and are getting. Here's an excerpt from the Freedom of Form Foundation, a "morphological freedom" group which is a tax exempt charity. They sponsor and promote otherkin research to literally turn people into furry freak shit. If you understand CRISPR and other genetic tech hyped by transhumanists, they stand a very realistic chance of being able to accomplish this within a century or two, at least to the degree troons can turn themselves into the opposite sex. Because transgenderism is just the tip of the transhumanist degeneracy iceberg, and that's where science is headed. The Freedom of Form Foundation is like the early gay advocacy groups in the 50s--at this rate they'll be hailed as pioneers.
Or how about AI? AI is a fun tool and one which might make a lot of entertainment better, but it's also gonna automate away most jobs, take away our cars (mandatory self-driving cars), and create a world where any evil corporation or government can launch a propaganda campaign on a budget while waving away all their misdeeds as "AI disinformation." They're already laying the groundwork to do this.
Or space? Space exploration and colonization is good, right? Except every space colony is a self-contained environment which you can never leave (lest you quickly die of lack of oxygen or thirst) and in which the people in charge control even the air you breathe. They can pump you full of CO2 to dull your senses
Watch this video from Youtuber and National Space Society president Isaac Arthur where he uses math to determine that if creating a deadly AI has a given chance of happening in a year, then it will happen on several planets every year, but this is somehow better if we have a whole galaxy since "only" a few solar systems are totally destroyed every year. This is a guy who is optimistic about technology to the point of ridiculousness that even he says that entire solar systems might be wiped out and more or less says it's "part and parcel" of colonizing a galaxy.
Let's not even get into Internet of Bodies.
@Drain Todger has covered that very well and cites the actual papers of Charles Lieber (CCP asset), Josep Jornet, Ian Akyildiz, etc. who are making great strides toward the hackable humans that Klaus Schwab's best bro Yuval Noah Harari desires. It all ties in with 5G and its successor 6G tech and the effects of terahertz radiation on what can be assembled within the body using cellular antennae assembled by the body itself using mRNA tech.
Point is, YES WE FUCKING DO. If humanity--or literally any species on Earth now--is to survive, we must ban all future technology research, monitor every science lab, and enforce it with the threat of immediate execution and nuclear destruction. Like this is the one and only good reason for a world government I can think of--stopping all future innovation. Although ironically you might need slightly better tech than today, like abolishing all power plants and force every nation to use energy from solar power satellites.
Now that you mention it I'm fairly sure imperial Japan also tried to isolate itself from the Western imports, like guns, which threatened the very core of their societal norms.
It didn't last and they eventually gave up.
And it created a golden age for Japan, which had since 1331 been more or less in a constant state of war. After Tokugawa Ieyasu consolidated the country, there were practically no wars until the fall of the Shogunate 250+ years later which was unprecedented not only in Japanese history but pretty much anywhere in the world. The population massive expanded, all sorts of industries developed, and Japan became a proto-industrial society on par with most of continental Europe.
They didn't ban guns either, they were a fundamental part of the Tokugawa Shogunate's military who maintained a network of armories and ordered many samurai clans to train in firearms. But since there were no wars and most conflicts could be dealt with through a swordfight or two against the dissident since muskets are heavy, people preferred swords. Can't whip out a musket/old-ass black powder pistol on command and behead a peasant, but you sure can do it with a sword (and since it takes more skill to learn well, shows you're a true elite). They also did cautiously accept foreign learning like the
rangaku scholars (imported Dutch books since the Dutch were allowed to trade with them in one port).
It's a great example of why Confucianism is an effective ideology (since this is the ultimate example of conservatism in practice) and why IMO the human race will need to borrow elements from it to fight the menace of technology. The establishment of a Confucianism-esque society worldwide could very well result in nigh-endless peace. Technology is a major cause of why empires rise and fall, after all (i.e. "gunpowder empires" or the conquest of the world by Europeans), so no more tech = a very stable and conservative society. The best examples of Confucianism in practice, Joseon Korea and Edo Japan, both fell because of external powers, so if a pseudo-Confucianism (IMO Confucianism has some problems and does need to be adapted to non-Sinic societies) dominates the world than the only external powers are the ayyylmaos and we're probably safe from them for a very long time.
