The current practices have originated from long research
Technically true, but only in the sense of "have originated as a side effect of long research in other things", rather than "have originated from long research into the most efficient or easily understood practices".

Agreed. But judgement can't be passed on efficiency and/or clarity based on opinions of people who don't follow the trade.
If we are talking about Mathematics, its going to look strange to people who don't follow it. Weird symbols and horrifying looking formulae are the most efficient and clear form of describing Mathematics - and its actually pretty clear to people who follow them.
