Why aren't (most)Indian startups working on anything substantial?

Most of the startups I see are mostly ubers or Amazons of something, or rip offs of other tech companies, or some other bs like "wealthtech" or "propertytech". Why are Indian startups (and businesses like Tata or reliance) so operations and commerce oriented , and obsessed with ADOPTING tech developed by the west but not CREATING tech that can be patented and give us an edge on the global scale?? One might say that we lack funding but most of the funding that I see does to blinkit or Zepto, there are very few ones in deep tech or semiconductor design. We really need to change this, else we'll be nothing but mere consumers and spectators of all the advancements happening across the world
