There are no incentives for bottom of the barrel programmers to write efficient and effective code, particularly when hardware in general have gotten so powerful and their own dev machines are probably overpowered for purpose.
The market doesn’t care. Making the program run in 1 second instead of 2 seconds takes the same effort as adding a new feature. The new feature empowers users more than saving a second, where they have the option of just buying a faster computer if they care.
There are always options. And always those looking to exploit untapped opportunities. And in the subscription age, you don’t refund, you just stop renewing.
There is no market for a photoshop competitor with half the features but runs faster for example. Because every tool is already tuned to be just fast enough that customers are satisfied.
