Big companies and the future of innovation

Another thing that is becoming more obvious is how much of the AI market is controlled by large technology companies.
Building advanced AI systems requires huge amounts of computing power, data, infrastructure and money. This creates a situation where smaller companies, researchers and independent developers can find it difficult to compete at the same level.
This makes me think about what happens to innovation when the technology becomes concentrated in the hands of a small number of companies.
Large companies can also acquire smaller companies, buy their technology or invest in promising ideas. Sometimes this is good because it gives small companies the resources to grow. But there is also a concern that independent inventions and ideas can eventually become controlled by much larger companies.
The question is whether the future of technology will continue to be driven by many independent people and small organisations, or whether it will increasingly be controlled by a few companies that have the money and infrastructure to build the biggest systems.
