To quote:

Time estimates matter not only to the business but they’re a reflection of your level of expertise as a software developer. An experienced software developer can keep tasks on schedule and communicate delays in advance.

I have 51 years as a software developer. Time estimates are worthless.

That's not really a great counter argument, can you explain why you think time estimates are worthless? Do you prefer story points instead? How do you schedule a project with your clients?
