look at linkedin (owned by microsoft unspiderable by all but google/bing). github (now microsoft using this to fuel its AI coding buddy, but if you try to spider this at capacity your IP is banned) facebook (unspiderable) .. the list goes on and on ..
and as you can see, data is required to train advanced AI systems, too. So big tech has the advantage there as well. especially when they can swoop in and corrupt once non-profit companies like openai, and make them [partially] for-profit.
and to rant on (yes, this is what i do :)) it very difficult to buy a computer now. have you tried to buy a raspberry pi or even a jetson nano lately? Who is getting preferred access to the chip factories? Does anyone know? Is big tech getting dibs on all the microchips now too?
