Why are we still using discs instead of cartridges?

The only (and most important) obstacle for these hypothetical cartridges would be their production costs. Otherwise, they could very well be superior. No scratches, no install times, faster and more quiet data-reading, etc.

Perhaps dev based carts could be made to cut the cost? (32GB carts for devs with around 32GB games, 64GB for the bigger ones, etc).

Yes but the savings you'd make on the rest of the console and not needing as expensive of cooling systems and other things would probably offset the production costs, at least based on that guy's perspective.

Isn't the cooling for the heat generated by the CPU and GPU rather than the optical drive?
