Given how many person-years have been saved and how much value has been produced by "slow, bloated, inefficient software", I must disagree in the strongest possible terms. Producing "slow, bloated, inefficient software" is far, far preferable to not producing software at all.
I would rather have no software or write the software myself than waste all the time of my life I've had to waste because of such shitty software, and it is indeed the case I've had to write such software from scratch because the alternatives were utter garbage. So we deeply, vehemently disagree.
