I hope so. I just see Apple going down the same dark path they used to before the M series laptops.

It's a reasonable concern and something to look out for in reviews and user reports. Hopefully they aren't repeating that mistake.

I heard that was a result of them designing for certain thermal envelopes ahead of time and Intel then delivering chips that didn't meet the specs they were promised. Not sure is this is what happened though so take with a grain of salt.

If this was the case, one the one hand they should be criticized for releasing such bad laptops on the market but if they had already decided on developing their own silicon then maybe it made sense to just accept that some generations of Macbook were going to have thermal issues and focus all efforts on the future.

That would be excusable for a generation of macbooks. Not over multiple generations.

Correct me if I am wrong but the heat problems were essentially Intel chips in the mid to late 2010s right? They are all essentially the same chip design with small window dressing added each year. The underlying problem is the same. Old design that suffered from Intel's issues in their fabs.

Yes, but there was ample time for Apple to re-design the thermal system of their macbooks. Instead they kept releasing extremely thermally limited devices year after year.
