This may be better explained through the lens of different departments within mega corporations. Alphabet constantly changing their messaging platform is bullshit, but their aggregation and ui for viewing not just the entire world maps but creating timelapse views of the planet is quite innovative and just one of thousands of research projects going on under their umbrella. Meta creating yet-another messaging clone in Threads is bullshit, but the research and development in optics and other fields as part of their VR work is actually quite cutting edge. Outside of tech there are also massive research bodies working behind the scenes. The recent adoption of decades of work in mRNA is a huge leap forward in vaccine work, for example. Many large corporations have these internal groups pushing the bounds of physics, and the scale and specificity of research today is orders of magnitude beyond where we were in the early half of the previous century. As we look back at the turn of the next century, I expect there will be a laundry list of technological turning points which are credited to today’s companies which just aren’t apparent in the din of 24/7 news and information. OTOH, thanks to these mundane communications services, we no longer need just a couple of research centers and, instead, we benefit from a larger network of investigators scattered about the world.
