That is utterly pointless. There was not a single straight-line of European scientific and social "progress" happening at a constant rate from 1500 to 1800. There was, broadly speaking, technological parity until round about the late 17th/18th centuries, and particularly in the military sphere after the 7 Years War. This doesn't have any bearing on most events during the EU4 timeline.
Actually, it is a single straight line. That's how the tech system is set up. That's why the tech tree is only measured in three categories. Those categories are the ones in which Europe excelled and the rest of the world, not so much, They're also the categories that were the engines of European progress. Broadly speaking, they are weaponry, seafaring and government administration. The EU series is ONLY interested in the areas of technology in which the Europeans were leading the world. And yes, there was technical parity until about the 17th century. That's why the period of European expansion really kicked off then. Therefore, European technological expansion should start to get pronounced at that time, which it was designed to. Mind you, you're talking about Asian technological parity, not global technological parity. The natives in North America never had technological parity (or not in the period where they had independence.)
The Samurai were a social class. That has absolutely nothing to do with the nature of Japan's technology.
Yes, and should we say that Knights were still running around with 10th century weapons until the 19th century, they'd still appear to be backwater. The Meiji Restoration happened and it was a triumph over the traditionalist factions in the country, namely the Samurai. Likewise, the reason why Oda Nobunaga is remembered in that country is because his willingness to break with the static traditionalist aristocracy, bringing in a meritocratic order that saw the a peasant rise from sandal bearer to be seen as a "great unifier of Japan". Ironically, that same peasant also re-entrenched the caste system and by the Tokugawa clan came to power, we saw the ejection of Western influences in an order to maintain an order that persisted to Admiral Perry shook up the country in the 19th century.
Ye-es, but they were rather peripheral to the world-trade system. They're not really an apt comparison for the world as a whole, especially given the very limited and formal systems of warfare in southern Africa pre-Shaka.
I included them to not leave out a region of the world. They did live on a major trade route, so if they weren't central in the world trade system, it is likely because they were too technologically primitive to contribute any meaningful amount. They lived on Indian trade route. It's not like they're Amazonian tribals.
Oh, bullshit they did. I'm not well-versed in the Battle of the Nile, but no way was the loss due to "a lack of understanding of the power of firearms". They had firearms, they'd been using them for centuries! And they were hardly unfamiliar with modern flintlock weapons in that part of the world either.
They might of had fire arms for centuries, but they fielded a primarily cavalry based army against Napoleon. Something you would never have seen a European army do in that era (or since) because the age of Cavalry as a central piece of the army had already passed by the 19th century. Again, it would be like fielding an army of Frankish knights. That isn't a legitimate tactic at that point in history, and if you were used to dealing with those sorts of weapons, you would absolutely know that.
Also small-scale and peripheral to the world-trade systems, and a society limited in that period by its nomadism, but it should be noted that they did also use firearms.
Again, I included them to show that Europe was the exception to the global trend and not the rule. If you want to cherry pick examples by throwing on conditions to skew the results until you have something that reflects your chosen world view, fine. I'm refusing to do that. I'm using examples from across the globe and a diversity of political, economic and social conditions to show that in the frame of the game, the only people who made any meaningful steps to modernisation were Eastern Europeans.
You mean the battle that was won because of a large chunk of the Bengali army betraying the Nawab? Not the best example.
There definitely were Indian victories over the British in that period.
Disunity and infighting in the subcontinent and British exploitation of the same was far more important to their victory than the technological aspect. Similar to Cortez, really.
And yet at the end of the time frame, India was a British colony. The British still also won Plassey.
For the stats, Plassey had 3,100 on the British side and 62,000 on the opposing side. The British loses (killed) number 22. I mean, the British also lost at Isandlwana, which was much more dramatic and that's the only reason why Rorke's Drift was even significant. Mind you, Isandlwana had about 2k British soldiers fighting about 10-15k Zulu Impis. Then again, Rorke's Drift was about 150 British soldiers defending themselves against about 4,000 Zulus.
I can understand that someone might take a decolonist or postmodernist stance on history, but when it becomes revisionist for the purpose of discrediting someone you dislike, it crosses the border into propaganda and, more likely than not, dishonest.
(The arguments beyond this have not been addressed because they became mostly unquotable due to a formatting error. While I am sympathetic to the fallibility we all live with as human beings, I am not disposed to take my time to correct said error.)
Having Said All That:
I have been reflecting on this issue and I believe I have reached a solution to the problem. The ROTW should have tech penalties. However, the AI, especially in Asia, should be encouraged to spend their points on development of provinces, which more accurately represents the advancement undertaken in much of the world. The Asian countries should be able to field incredibly large armies and these provinces should be rich and produce a ton of goods. They should not be able to field modern armies or build European Stock Exchanges. They should be hard to convert, both religiously and culturally, and cost a lot to take single provinces out of a country like India or China, both in terms of warscore and overextension costs. Therefore, the Asian provinces should have huge discounts in terms of development, but penalties in terms of technological development.
