Masayoshi Son, the founder of SoftBank, once achieved remarkable success in the mobile internet era with his unique investment model. However, in the current AI wave, SoftBank's investment strategy has become more conservative, missing out on opportunities to invest in several AI unicorns. Son himself shows a strong interest in the AI field, but SoftBank as a whole remains in a state of confusion. The frequent turnover of SoftBank's top management has created a succession dilemma for the company. The industry's downturn also brings difficulties to SoftBank. Both SoftBank and Masayoshi Son are striving to find their place in the new era.
