The BlackBerry era is over. Once a high-flying tech giant that played a key role in the mobile device revolution, BlackBerry failed to innovate in a rapidly evolving consumer technology market and eventually failed spectacularly. Now, Cardano creator Charles Hoskinson warns that Ethereum could be next to fail. Hoskinson believes the world’s second-largest crypto will not survive over the next 10 to 15 years as users migrate to other blockchains and design flaws persist. Hoskinson: Why Ethereum Won’t Survive The Next 10-15 Years In a recent AMA session , Charles Hoskinson claimed that Ethereum’s accounting model, virtual machine, and consensus model are badly designed — a triad of architectural flaws that he thinks are a bane for the blockchain network’s survival. “People told them not to do it, they did it, and they got where they needed to go,” he said, before warning that the fixes adopted so far “put in all these weird slashing economics and layer twos and other things,” whose unintentional outcomes are starting to bite. “I don’t think Ethereum will survive…more than 10 years to 15 years,” Hoskinson asserted. Hoskinson, who helped co-create Ethereum in 2014 before leaving to launch Cardano two years later, emphasized that Ethereum needs first to solve its technological issues, pointing specifically to its proof-of-stake system as something the network “needs to wean itself off,” as it is not built for long-term success. Hoskinson also slammed Ethereum’s layer-2s, which are driving activity away from the main chain. He described these L2s as “parasitic”, predicting that they will continue to suck all the alpha out of the main chain. In his opinion, Ethereum does not have a good on-chain governance system that would help solve the aforementioned issues. “People will start fighting, and it’ll get harder and harder for Vitalik to be able to hold it together through sheer force of will, and users will gradually migrate to other places, and then they’re going to get eclipsed by Bitcoin DeFi,” the Cardano founder added. He conceded that Ethereum is a “brilliant project,” but like Myspace and BlackBerry, the crypto could fade into oblivion as newer, more efficient systems take over. “It’s just a victim of its own success, like Myspace or any of these other things that have a lot of network effect and momentum. Blackberry is another example,” he stated. “And the other thing is they’re eaten alive by Solana.” ETH Price Underperformance Hoskinson’s comments come as Ethereum has underperformed the broader crypto market. Specifically, the token is down over 40% against Bitcoin since the beginning of 2025. Ethereum is up almost 1.8% on the day, currently priced at $1,791, as of press time. The industry’s second-largest crypto by market capitalization has had a bumpy stretch lately, sinking around 14% over the last 30 days and more than 42% since this time last year. But ETH is seeing green today, at least.
