Strictly as a thought exercise, consider how often you find yourself saying "No offense intended."

The person you responded seems like most of "us" - most of us aren't ML experts. He humbly shared his experience with dipping his toe in the ML pool and reported back that he (metaphorically speaking) had to chip the ice off the pool before he could even get in.

This was useful information to "us" (non-experts interested in learning about ML). Calling his difficulties "trivial" for an expert in the field while true, came off as condescending. Telling him (him!) to check his ego came off as egotistical.

No offense intended. ;-)
