The expressed (not implied) alternative in the post is for those people to stop pretending they care, and start actually caring. Stop trying to save the world. The world doesn't need an invention to save it. Just put that energy into caring about others.

People do care, but there are so many problems in the world, and only so much caring to go around.

It's extremely cynical to view it as "people pretend to care", rather than looking around and realizing there's a ton of important problems out there that the caring is distributed over. People care about disabilities, but they also care about war, about public schooling, about the environment, about feminism, about animal rights, about transparency in government, about road safety, about child well-being, about unemployment, and so on. All of these are important things, and of course there are dozens more that I haven't listed.

And inventions are sometimes actually useful. Sure, most of those prototypes will go nowhere, but every once in a while something that really helps is invented. And you can't predict in advance only the ones that will actually go on to help.

Holy smokes, that comes across as "We just want all people to be impoverished equally".

Some people actually care, but they can't always win the battle at their own companies when there are other priorities, much less go fix all the other websites, pour concrete at other businesses, etc. Is the solution for everyone to care? If, so how do you accomplish that? ("Americans with Disability Act" v2?)

The world doesn't need an invention to save it. Just put that energy into caring about others.

This is an excellent summary of the sort of anti-tech thinking that I strongly disagree with. Caring about people with Alzheimer's is well and good, but what we actually want are vaccines and cures.
