If I used to provide some value X in a day, and that was enough to cover my consumption for the day, but now others are providing the same value X in 5 minutes, it will not be enough to cover my consumption for the day anymore
Sure, but we are not talking about evaluating your contributions daily. Over a lifetime, people find new ways to provide more value. Life is long, and that is how adapting works.
We don't all sit at typewriters anymore either, but former typists found other ways to provide value, I'm certain, and didn't just disappear and become homeless (the vast majority of them, anyway).
Once upon a time, we had armies of secretaries that secretly (well, not so secretly) were the backbone of every institution. We don't have that anymore either, since computers replaced many of them.
Computers were originally people. They also got bested by new technology.
None of those people disappeared or became destitute; they adapted, and they found new ways to create more value. (Or, it's possible some ended up working for rent-seeking corporations, which is a different point)
