I think that ethereum will never gonna die knowing that many big corporations, instutition and companies are not getting interest in investing in crypto most especially with bitcoin and ethereum. Regarding the gas fee of ethereum I think that ETH 2.0 already did some adjustments just to fixed this problem that the ethereum blockchain is having.
Unfortunately, it looks as if the adjustments were not good enough. The gas fees is still quite high. A few days back, it was going at 250+ Wei, and now it has come down to 100 Wei or so. Anyway, the users are still afraid that they will again witness sky high fee, such as the one we had in June-July, when the gas fee reached 700 Wei. It is like a double whammy. Both the gas fee and the exchange rate for ETH has risen. So the user ends up paying a much higher amount when translated to fiat currency.
