Computer science is nowhere near its maturity as a whole. It needs more people with ethics and empathy. We've seen what has happened without that factored in; we're living in it.

Innovation as a goal sounds noble initially, but in my experience it's like chasing the wind. Faithfully doing what is already known to be good seems better for everyone. It might even be the quicker road to innovation.

To your first point, software and computer science are in their infancy. To say software has reached its limit speaks of the abilities, and imagination of the author.

As to your second point, we did have people with exceptional sense of social responsibility in software, but multiple factors, including easy/fast money, unspoken agendas, both co-opted and corrupted some, and drew in 'fresh blood' that was motivated purely by the new social cachet & easy fortunes of software work. (These are the ones Alan Kay would say are the 'pop artists' of 'pop software'.)

As to innovation and "limits", there are legion and everything from the hardware, OS, libraries, to languages are on the table for innovating, to say nothing of theoretical breakthroughs in pure comp-sci.

Software is the closest thing to magic we have in the modern world. The imaginal sky is the limit.
