No, it is not. Bitcoin works fine without any further changes. Surely it would be nice to have more TPS. Would Bitcoin die if it didn't attain that? No. Honey badger doesn't really care.
it works, but not fine... We have had queues that last for hours(10+) to confirm, and if every time that happens we have to raise fee's... give it a year and nobody will be using bitcoin.
i remember lauda getting very excited about a game "world of tanks" accepting bitcoin as payment.. but soon after he went very quiet and dismissive when reality sunk in, that players would have a headache actually trying to buy things with it.
lauda's mindset is a road with a pot-hole every 100 yards is still a fine and working road because all he can see is cars driving on it. he has no concept of the axel/suspension damage the pot holes can cause or the wheel rim damage. or even just the discomfort to the people in the cars.
to him he would not care about repairing a road. he would rather make people be detoured to a parking lot and then commute by bus(LN)
