In the last ~10 years humanity has developed:

• electric cars
• mRNA vaccines
• cars that can (more or less drive themselves)
• convincing human language text/speech synthesis
• reusable space rockets
• precise gene editing
• prosthetics that directly connect to the nervous system
• robots that can walk across inconsistent terrain
• commercial quantum computing and quantum cryptography
• cultured meat
• biometrics
• computer vision
• virtual reality
• optical computing
• wireless charging
• stem cell treatments
• neural computer interfaces
• drones
• maglev trains

New technologies tend to have long lulls while being developed, followed by a rapid series of developments when those technologies become viable and in turn provide the base for new technologies.

Yeah, there's always grifters and technologies that turn out to not be useful, but there's also always tons of people working really hard to create new advances for the benefit of mankind. Capitalism is definitely flawed (understatement) but relative to say, feudalism, continues to be a very efficient way to allocate resources when used in a well managed economy.

Capitalism incentivizes risk-taking, which can be productive when there are potential opportunities that are otherwise too risky to explore.

But after they’ve exploited the productive risk/reward opportunities, capitalists increasingly rely on amplifying the risks—but there’s no longer any commensurate increase in rewards, at least for society as a whole.

I think you don't have a good definition of capitalism. Let us define it as a system where a small group of individuals (capitalists) control the means of production, and everyone else (workers) creates value, most of which they don't receive... That in itself has nothing to do with corruption. It has nothing to do with stagnation.

And the examples you gave were about innovation, and innovation happens in many non-capitalist systems, too. No reason socialists can't innovate, is there?

But what we also see is that capitalists hate capitalism. They have to compete, they could lose. So invariably they try to seize power in other ways. Therefore, one could argue (and many have argued) that capitalism leads to (or is likely to lead to) fascism.

At the same time, understand that any system can be corrupted. Some are less stable than others, but we always need to keep an eye out for the shady selfish jerks.

Ah yes that's why North Korea was so much worse off than South Korea in the late 40s and then became so much better. Oh wait no, the capitalist south started out worse and is now better than the feudal north.

any new power structure can be good for the time it takes a generation to pass. after that people forget why they designed something a certain way and lose engagement with the political process. the only political and economic system that will ever be functional is one that is fundamentally founded on educating the populace on both their right and their responsibility to be involved in their own governance. the right to bear arms was a prototypical move to ensure people would always be able to enforce their right to self governance but without education in the importance of actually doing so it has ultimately failed to fulfill that purpose.

as long as they think its profitable, thats why alot of research universities have to practically beg for money most of the time.

You might be interested in Kondratiev Cycle‘s. Those cycles are running 30-50 years. We are in the end phase of the IT cycle and begin of a new one. At the peak of those cycle‘s were always market dominating companies. Many of them were broken up by governments.

I assume the new is about regenerative energy and material production.

Capitalism started in the Victorian era

I agree with the sentiment, but I disagree that technology has "peaked".

Technology constantly grows, and it's moving faster now than ever. We won't see the peak until society collapses and all the systems required to fuel that technology fall apart.

You're writing this from device produced by that filthy capitalism
