I rather see people invest in harder world problems (battery capacity, co2 sequestration, habitat preservation, humane recycle programs, cancer research ) rather than the next copy of x.
I'm not saying that things such as pagerank, dynamo, bigtable, mapreduce and tensorflow aren't innovative but most things are just remodels of old concepts ("AirBNB"for machine tools).
Which lets be serious anyone with a good open source webstack can reproduce.
The current web state reminds me of the smartphone/camera manufacturers desperation to push more sales.
Buy, buy, buy, Oh please buy our 16MP cameras even though the human eye can only process around 8 MP.
Tech companies are desperate to win more users/profit channels.
