It has been several episodes that I feel that civilizations (human and alien alike) do not progress in normal pace. Discovery jumped 930 years in the future, yet the technological advancement in the 32nd century seems minimal compared to the 23rd century. Case in point, the starship engine. Putting The Burn into consideration, in 800 years, civilizations in the universe were still using dilithium-powered warp drive. The basic design and architecture of starship propulsion did not change in 800 years. Compare that with real life where 800 years ago our ancestors went to the sea with dhows and junks and now we have nuclear submarine. Or compare that with in-universe where warp drive was invented in 2060 and in 200 years they had full-blown space exploration. I would think that in the far future they jump from system to system with hyperdrive or something.
As well, our Discovery crew seem to be able to match their 32nd counterparts in terms of knowledge, medical, warfare, technology and many other things. Again, back to real life example, imagine if there is a ship from the year 1090 appears here and meet with a modern destroyer. Just one shot and that ship will be blown to pieces without any resistance. In short, I am a bit disappointed with how the show pictures the 32nd century.
