Discussion on question by anonymous1: My boss wants me to recreate everything I have done for my previous employer

How does your new boss expect you to recreate the models without your old employer's data to train it on? If you don't need proprietary data to train it, I don't think there's a conflict necessarily.

@anonymous1 So you get to decide if you want to continue working for a company that is asking you to do something you believe is morally wrong. Only you can decide what your morals are worth.

Did you have a non-disclosure agreement with your former employer?

Did you only use public datasets to train your model or also data from your former employer that you can't recreate from memory?

If this knowledge is so valuable, why not go into business for yourself?

@AndreiROM Because depending on where you live, setting up a business for yourself, finding the relevant customers, getting everything in order and handling the administration is simply very frustrating to do.

Although I understand your legal worries, I don't get the ethical concern (other than if it is illegal or dishonest). Using the ideas in the new business doesn't stop the old one from using them.
